When a guy is giving it to a girl from behind and he substitutes his friend in right when he's about to cum. He runs outside and waves at her through a window. She is left wondering who the hell is fucking her now.

Casper might not seem to be an appropriate name for a K.I.D.. But be sure, that when you meet a person called Casper, dont be in doubt.
These so called ''casper's'' is down with everything.
(Almost everything)

They will most likely seem friendly and calm to everybody, but if a mofo is messing with him, be sure to get Casper out of the room, hall, etc.

Also, these persons are very rare, and will most likely only be found in their hood. controlling whatever they do.

When in doubt of the person is really a Casper or not, kick him or slap him. If he is a Casper, he will most likely make a dickish move, either when you are trying to impress a girl, or just when you'r trying to do something cool.
*SLAP*
''Hey guys guess what i did last night'' - (one of the mofo's slapping a Casper)
''I dunno dude, but guess what i did last night'' - sticks his 'two fingers' up close to ur nose and yell out - ''YOUR SISTER''
