The act of screaming HIP CHECK next to a random stranger in a very deep, seductive voice, then performing said action on said stranger. You then perform a quick party boy on said stranger, and proclaiming your new ownership of this "Hipchecked" stranger.
Spagett walked down the hall when he saw some fat guy. He walked beside him and said, "HIP CHECK!' While slamming his hip into this fat man. After the check, Spagett party boys the fat man, and proclaims his ownership, or says, "YOU MY BITCH NOW FOOL!"
