T-money Millionaire 's definitions
When you are fisting a girl's asshole and you pull your hand out with a turd and when opening your fist it explodes in your hand (blowing up like a gernade).
I was pleasuring my girlfriend's butthole when I pulled out my hand and the Horsham hand gernade went off.
