A (now) mainstream four-piece band categorized as pop punk, pop rock, emo, or combinations of the three. Known for their nasal vocalist, simplistic guitar riffs, basslines consisting of no more than four notes which cannot even be successfully played at a live show, and "poetic" lyrics such as "WE'RE GOIN" DOWN, DOWN, ENALURBLYURAAHLL...", it's no surprise that Fall Out Boy is one of the most popular rock acts today, particularly among 14-21 year old females and males confused about their orientation.

Fall Out Boy differs from similar bands in that their bassist acts as (or tries to act as) the frontman of the group, without singing or adequately playing his instrument. Though he ranks as the least talented member of the band, Pete Wentz garners most of the group's media attention, being the only 6 while surrounded by 3's and 4's. Pete also writes the "brilliant lyrics" indecipherably crooned by singer Patrick Stump. In an attempt to appear quirky and clever, titles of Fall Out Boy songs are usually a sentence long. The exposure of Wentz' genitalia is irrelevent and was likely brought to the media forefront by the band itself as a failed publicity stunt.

Taking note of the band's lack of... everything, it is a mystery how Fall Out Boy is successfully marketed. There are no timeless hooks, no particularly attractive band members to get the teenyboppers riled up, nothing instrumentally impressive or innovative, and nothing that hasn't been done before several times (and with less ego) by Blink 182 or even Simple Plan. The success of Fall Out Boy remains an enigma, as well as a trademark of the tastelessness of teenage youth and anyone who refers to themself as emo.
Fall Out Boy is MySpace on the radio.

Originally the sidekick to Radioactive Man in the Radioactive Man comic series on the Simpsons. In the film version of Radioactive Man (starring Ranier Wolfcastle) Milhouse was cast in the role of Fallout Boy.
Bart: Well, between us we've read all 814 issues of "Radioactive Man."

Milhouse: Yeah, and we both have the special limited-edition issue where he and Fall out Boy get killed on every page!

1. A Chicago-based band whose sound is characterized by crunchy metallic riffs and by stop-start rhythms, as well as sometimes cheeky, sometimes emotional lyrics.

Could be (and often is) described as part of the modern pop-punk emo movement, though it has to be noted they are far more rock-oriented and electrically charged than self-admittedly emo bands such as Dashboard Confessional.

Started out fairly indie but has since gained a huge mainstream "pop" audience.

Biggest hits include: Sugar We're Going Down, Dance Dance

Similar bands include: Funeral For A Friend, Panic! at the Disco

2. In the popular TV show The Simpsons, Fallout Boy is superhero Radioactive Man's sidekick.
1. Did you check out Fall Out Boy's new CD?
2. "Radioactive man, look out!" screamed Fallout Boy.

Fall Out Boy is a Chicago based band, that actually had a life before MTV.

It has four members; Pete Wentz, Patrick Stump, Joe Trohman and Andy Hurley.

For those of you who think Fall Out Boy are emo posers; they aren't. They aren't even emo, and, like I said, had a life before MTV. It's MTV that made them so popular, along with some air headed teenage girls, who only listen to them because 'PeTe Iz SoOoOoO hAwT!!!!!11'.

Oh, and by the way, there is no 'Tom' in Fall Out Boy. On the From Under The Cork Tree album, some tracks were mixed by Tom Lord-Alge, which could be the cause of this misconception of the invisible 'Tom'.
Normal person : Air is leaking out.

Here's an actual defenition, not JUST an opinion

A band from chicago formed around 2001. It consists of pete Wentz, Patrick Stump, Andrew Hurley, Joe Trohman. They are not I REAPEAT NOT, and emo band(see the get up kids for some). If anything someone could call them Pop-punk. In my opinion a very good band who's fans actually go deeper than what most of you think. Fall Out Boy did exist before they were on TRL, therefore their fans existed before TRL and thefore do not consist only of 13 year old girls who love guys in gril pants.

Catchy guitar riffs and unique vocals make their music better than anything you and your crappy yamaha bass could put out.
Urban dictiony person:Fall Out Boy is SOOOO Emo.
Actual intelligent Fall Out Boy Fan:You Fucking Idiot, no they aren't, listen to the lyrics you dumbfuck.

A band, not a "gay shitty ass emo band", a band. That's what some of you guys keep on posting that and we all get it, you don't like them, they may not be worthy of your time, but they do deserve your respect. And you go far enough by saying "all their fans are retarded emo faggots" when you don't even know who half of them are. Just because people like them, doesn't mean they're all "emo", "retarded" or "homosexual."
person 1: Fall Out Boy sucks ass! They're such gay, emo faggots and their fans are retarded!
person 2: Shut the fuck up, all you ever talk about is how much Fall Out Boy "sucks" Gosh, they're just a fucking band, Why waste your life complaining about it, Quit being so bigoted!!!!!!!!!!!!

1: Fall Out Boy are a band from Chicago, made up of four members... Peter Wentz, Patrick Stump, Andrew Hurley and Joe Trohman. Due to certain lines in the songs, they are considered EMO (by people who need to be shot), but they are actually NOT. They are critised alot for Patrick Stump's lead vocals, apparently, being "horrible" and "hard to understand". The answer to this is, of course, get your fucking ears cleaned out because if TONS of people can hear what the hell he says, why cant YOU?

2: A fact that is NOT known to many people, is that Fall Out Boy actually had a LIFE before MTV. And It was not up to the band to have hundreds of stupid airheaded girls constantly asking for their music videos to be played on MTV due to the fact that "Peter is so HAWT!!!" If you are going to blame somebody in that situation, blame MTV. Or better, the stupid airheaded girls.
1: Sugar We're Going Down: (before your ears get cleaned out) Wee goh in DAH DAH in ah earlieeh rauh! Shu gah wee goh in dah swing ih!

Sugar We're Going Down: (AFTER your ears get cleaned out) We're going down, down, in an earlier round. Sugar, we're goin down swingin.

2: Bimbo: OmmGzz! Petah from Fall Out Boy is So0o0o HawwwTT!
Sensible human being: Stop checking out the members, and listen to the fucking music, you dumbass. And by the way, its PETER!!!

The name is derived from the television show, The Simpsons, Fallout Boy is the young sidekick to the Superhero, Radioactive Man. Like Robin is to Batman.

The band Fall Out Boy is currently(2005-06) very popular. However, they give what is quite possibly the worst live performance of any major record label band currently out.

The guitarist and bassist insist on being in constant motion while on stage, including jumping in 360's, getting on top of amps, and jumping off of stage platforms, even though they are physically incapable of continuing to play correctly while doing so. The lead singer/second guitarist can neither sing, nor play guitar well, much less perform both tasks at the same time. This produces a stage sound and presence which is highly unnatractive, and very unpleasant to the ear.

Their songs are pop-driven, somewhat simple, yet varied, and feature many catch phrases that will be branded all over your friends' AIM profiles and Myspaces for the next few months.


"Drop a heart, break a name"

"I'm just a notch in your bedpost, but you're just a line in this song"

"Sugar, we're going down"

"We'r always siffee ee eida sefehh fodah roongg teeee"

As the last quote demonstrates, most of their lyrics, even on the studio tracks, are indiscernible to the common person's ear. But not the 8th and 9th grade girls. They can mysteriously hear all of the lyrics and find great, deep meanings in them.
Girl: "OMG i loove Fall Out Boy, 'Sugar We're Going Down' is the anthem of my lifeeee"
Guy: "I think we need to break up"
Girl: *sad face* "I'm just a notch in your bedpost, aren't i?"
Guy: "Yeah, seriously, we're not even going to be friends anymore."
