when somebody who doesn't have a girl friend or a loner shakes his special organ with his hand
Ever since Chris's girl friend broke up with him, he is relying on hand-pump.
Matt was doing hand-pumping whole night, he looks so pale.
Hand-Pump is the best way to satisfy yourself without spending a single quid and No-tensions as well.

Hey Delilah, have you seen Tim?
Ya, he's just in the car giving himself a quick hand pump.
Discovered by men but stolen by the female species at a horrid attempt to bargain with the opposite sex by attempting to offer something as a treat, when in reality, it is something very ordinary, manipulated by evil girls to make you do chores or give them flowers! The 21st century version of a kiss!
