When I was younger I often thopped my younger brother, forcing him to assume the role of thoppee.
A sharp rapping with the palm of the hand on the back of someone's head. A thop is commonly used when the thoppee has said or done something illogical or stupid, or it can be used as a threat.
'If you don't get yo ass here right now I'll thop you into next week!'
