Chimp Wank 

It is the act of taping ones penis to ones leg with either tape or cling film and wanking with his leg like a chimp.

The main advantage of this is that one can still eat and drink at the same time like a Sir.

Sir 1 "Dude we used so much tape and cling film"
Sir 2 "What having a chimp wank?"
