A small creature that fits in the center of one's palm and when frightened will scurry under the covers of one's bed. Dick Weasels become hungry very easily and should be fed often. Usually blue in color.
Dude, did you lose your Dick Weasel the other night, I found one in my bed.
A guy that tries to get involved in sex between a couple, usually in a sneaky fashion. He is not opposed to dp to get in between aforementioned sex, because as everyone knows, dp (whether softcore or otherwise) as long as balls dont touch, you arent homosexual
