An american band;also radioactive man's sidekick from the simpsons, also a term used on gay porn sets where they replace one boy with another who's willing to fuck an old guy.

Possibly the worst thing the world has ever turned out. Vocals sound like a baby crying hysterically while being repeatedly struck in the crotch by an electrified spatula. Fall Out Boy can be heard strumming their guitars frantically to try and confuse the listener into thinking that they actually know how to play their instruments. Fall Out Boy incorporates erratic beats and ear raping vocals into "music" that doesn't even flow through the course of one "song". Fall Out Boy is a group of girl scout rejects that got kicked out because they didn't make their cookie quota. hey if you're gonna suck at selling cookies why not music?

FOB fan-"hey did you hear that new Fall Out Boy song?"
Sensible Human Being-"you mean that noise that sounds like Wonder Woman being gang banged by a group of kindergarten Nazis??"
FOB fan-"yeah that one!! wait they all sound like that."

A band.
Genre is often argued but I would say pop/rock. Not punk or emo or just pop or just rock. Okay?
Consists of Patrick Stump, vocalist and rythm guitar. Can't play guitar very well (and I'm a fan) but although often sings lyrics indecipherally ('that a word?) has a good voice.
Frontman, Pete Wentz. Yes, he gets all the attention, he's the frontman, yes, he can't play bass very well and yes, it is the teenybopper fans who crush on him but I don't know many FOB-teenybopper-fans.
Andy Hurley, drummer and political activist. Currently writing a comic book with his friend. Now, how cool is that? I'll answer for us all: Very.
Joe Trohman, guitarist and owner of rockin' jewfro. Creator of 'Trohmania' and is rather artistic, in my opinion.
Girl 1: Oh my gawd, Fall Out Boy are so cool! You see they're this emo band and-
Girl 2:A-ha!
Girl 1: Like 'Take On Me'?
Girl 2: No, like that's a common misconception, they are not an 'emo band'. Emo is very different, both great genres.
Girl 1: You lost me.
Boy: I've heard they don't play well live.
Girs 1 & 2: We heard that, too.

A really crappy punk pop emo band that is most known for stealing their name from The Simpsons character Fall Out Boy. ( sidekick to Radioactive Man.)

Most known by emo kids who watch to much MTV and think it's cool to have their hair long and dyed black.
(also see faggy emo)
hey have you heard the new fall out boy song?
NO! cause i'm not gay!

A shitty excuse for a band: Their alternative style lacks in musical development. Their songs lack variety in rhythm, consisting mostly of sloppy thrashing power chords and smashing drums. They have absolutely no ability to pull of a decent live performance, and they lack improvisational skills completely. They can't jam, they can't compose intricate style with solos and whatnot, so FUCK THEM!, and all the similar punk-pussy bullshit out there.
BITCH: "Hey, have you heard the new fallout boy CD?"

DUDE: "No, why the fuck would you listen to that shit???"

BITCH:"Cause I'm a stupid narrow-minded bitch."

DUDE: "Good."

The Gayest band on the face of the whole mother loving planet

The definition of sell out. A highly overrated band with a horrible vocalist who cannot sing for his life. Pete Wentz is the only member of that band who gets any credit and i'm sick of hearing little teeny boppers talk about how "hawt" he is. It makes me want to barf. He looks like a monkey with eyeliner. I bet all 13 year old girl Fall Out Boy fans now despise Ashlee Simpson.
FOB fan: "Oh my gawd!!" Pete Wentz is so hot! Fall Out Boy is like soo amazing!!"
