look up any word, like smh:
 
8.
1:A white, adult, male, virgin usually suffering from some form of autism

2:One who pretends to be a hacker, although they're only capable of DDOS attacks on websites through sheer numbers, and occasionally defacing a myspace page.

True hackers crave recognition, after all.

3:One who hides behind anonymity so as not to be exposed for the sad, lonely, obese, gollum-like creature they truly are.
Def 1

Dude: "why doesn't he ever make eye contact?

Dude 2:"he must be a /b/tard."

Def 2

"gb2/b/ n00b!"

Def 3

"without /b/ i'd never experience any social interaction, thanks 4chan!"

One who has experienced true Hell on the internet. This person has probably already gone insane. Talking to them will result in your own sanity or IQ loss. Talk to a /b/tard at your own risk, newfag.
"Rofldance, dude, did you see Rick Roll doing Weegee on top of Heavy Weapons Guy last night while on the phone with desu girl? But man, I tell you, Vagineer is as almost as scary as Ceiling Cat singing double rainbow, all the way. Zeus Cat, I'm such a /b/tard. Lol, internet."

A pathetic loser!Typically a 18-60 year old male who can't get a date with a real woman. Often lives in a family members basement.
Usually a racist. Loves to play WOW and other gay role-playing games when not on /b/ or looking for porn.
Often found in 12-16 year old girls chat rooms on stickam, blogtv or some other webcam site. They think they are cool when they use misspelled words 4 code..examples..Pl0x, tiem, liek, nao, bewbs, noob, etc...little do they know that it really makes them look like an idoit. A /b/tard's favorite saying is Tits or GTFO. They say (type) it over 9000 times daily! /b/tards love mudkipz. They are the reason we can't have nice things. /b/tards are not disgusted by anything! They can watch a midgette get beheaded while fucking a dead horse covered in maggots, all while eating a sanwhich and laughing. /b/tards think it is funny to ruin someones life: Especially a beautiful young lady with a bright future. /b/tards are scum of the earth and are truely sign of how our society is failing in general. /b/tards are proud to be the scum that they are!
Did you see all those /b/tards raiding that poor girl's chat room last night? She was scared shitless! Those /b/tards found out all her info and threaten to come to her house and rape her! What a bunch of losers!

someone who spends all their time on 4chan's image board /b/.
this person usually knows all kinds of internet words and acronyms such as gtfo, newfag, oldfag, and candlejack (oh shi-).
a /b/tard can usually be seen by their knowledge of all things random, and their knowledge of fellow /b/tards.
hello anon.

tl;dr.
gtfo of my /--/ you /b/tard and get back to /b/!
