Lint Rolling 

The act of inserting a small furry animal into one's own (or one's partner's) anal cavity.

Richard Gere and I had fun doing some lint rolling last night. I sure do miss Fluffy though...

lint rolling 

when you take the lint from your belly button and put it into someone else's belly button. You do this action back and forth between you and that person's belly button lint.

Yeah man, we were lint rolling all night. It was sort of hot.
