Water Pistol

First of this is a idea inspired by cyborgHG.
He had the idea of having a water gun sniper or whatnot.

Myidea: Having a small water pistol (that shoots water) at your Key 5.
This would be absolutly useless, but...
You know how you own someone or you win a round and jump around knfiing, tea-bagging the person you killed or simply emptying your clip at someone's dead body.
Well how about pressing Key 5 and getting a water pistol and shootin their dead body.
How humiliating would that be, it will be great.
