this is a prank played by the male to the female. after sexual intercourse or whenever, the male goes into the bathroom lifts the toilet lid and jizzes on the seat. the white substance blends in with the white seat making it almost unnoticable. when the female walks in to use the toilet, she'll find herself stuck in a sticky situation.
Joe: Lucy didnt make me a sandwich last night so i pulled an Ass-hesive on her, haha
Bob: Nice, she'll be making sandwiches for sure now
