someone who jumps young women and slathers thier vagina in butter in order to steal thier wallet out of it.
suzie is walking down the street.... suddenly someone butterjumps her! thus knocking her down and pulling her pants down to get to her vagina.
Then she screams "Oh no! hes a butter jumper!!! i hope there arent any more Butter Jumpers!!!" :O
