Selin, Amada and Esmer's definitions
A guy that makes a girl wish she had never taken off her underwear. He's in and done in one pump. A total waste of a girl's time.
Selene was looking forward to the night and expected a night of great sex. However, the guy turned out to be a one pump jump and ruined the entire night.
