/b/tard 

One who joins other internet superheroes in the poasting of content on /b/. A true /b/tard knows all the memes of the land and is disgusted by nothing. A true hardened warrior.

7chan, 4chan, iichan, 12chan, that crazy russian /b/. It doesn't matter. We are one. Anonymous does not forgive. Anonymous does not forget. We are legion. We are Anonymous.

"Holy titanic hermaphroditic shitting dick nipples Cock Mongler, I must be a /b/tard."

because the idiots above pissed me off, here is what a /b/tard is:
a /b/tard is one who actively posts or lurks on the /b/ board at either 4chan.org, notfourchan.net, 7chan.org, 12chan.org, iichan.org, ebaumsworld, ytmdn or countless others. to those who it concerns, yes in writing this i am breaking rules 1 and 2, but you will get over it.
there is so much more to it than this, but that is all you need to know.

/b/ does not exist. Move along, sir.
a /b/ tard is the guy who tells the cripple ahead of him in line to hurry up.
a /b/tard is first to get to the window to see the car accident outside.
a /b/tard is the one who wrote your number on the mall's bathroom wall.
a /b/tard is a failing student who makes passes at his young, attractive English teacher.
a b tard is the guy loitering on Park Ave, the one that's always trying to sell you something.
a /b/tard is the one who handed his jizz-drenched clothes to Good Will.
a /b/tard is one who introduced you first to Goatse.
and so on and so forth
