Twi-tard 

Over the top fans of the Vampire series "Twilight". The kind of person who stands in line all day to get in to the midnight showing of the latest Twilight movie. Most likely they have read all the books and have picked a side... "Team Edward" or "Team Jacob." These people sometimes call themselves

Twi-hards.

Dude 1:Hey, so we going out clubbing tonight?
Dude 2: Ah no bro, I'm already on my way to see Twilight Eclipse at the midnight showing!
Dude 1: Wow, I never pegged you for such a Twi-tard!

Billy Ray-tard 

A southern person, like Billy Ray Cyrus, who acts retarded.
You could also just call someone who is being a jackass or is doing something that annoys you a Billy Ray-tard!

"You Billy Ray-tard!!! I told you not to call me Squirrel Boy!! God dang it!"

Double A Tard

One who either is a Big Book Nazi and preaches the book and has no life out side of AA. Or someone who isn't there for the meetings, there only there because no one else will be friends with them and now we have to put up with there shit.
Also some one who should go to other meetings maybe BB instead of AA (What's BB? ......It's not AA)

Ugggh Jesus you stupid Double A Tard, cant you just leave and go to one of those other meetings?

Clit-tard 

Someone, usually male, who is sexually inadequate and possibly has a tiny dick and is something of stranger to women's best friend that is the clitoris and couldn't find a G-spot on a radar.

Lad; "Hey baby, how about a good time?"

Lass; "Why don't you fuck off to whatever little fucking sewer you crawled out of you sad, pathetic, smelly, borderline queer little Clit-tard!"

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
