A move that signals to the opposite sex that you are interested in copulating. It is specifically done by placing one hand on the floor, buttocks in air, and then gyrating buttocks in a up and down motion. Usually made by someone of samoian descent that is under 5'4 and has been drinking heavily.
That girl totally wants to hook up with Albert. They were out dancing together and she did a trinnie.
