This is what I could find:
2lunchable1. An ignorant person whos top priorities are their drug intake, american football, eating at mcdonalds, driving their camaro/mustang and trying to pick up under aged girls. they cannot hold a conversation because they
burnt out their last few brain cells eating handfuls of pills (they dont know what was in them, they just eat them) and drinking cases of **** beer (ie, bud or
miller lite.) they are violent and frequent
run of the mill night clubs.
2. See meathead.
Still don't get the clown makeup...maybe a new offshoot of Insane Clown Posse?
