Shaurya Slap
When you are bangin a dime honey bitty from behind and you furiously strike her in the BASE OF THE SPINE. This causes her whole body to lock up into a massive seizure, and thus tightens whatever hole the man is profusely penetrating. Similar to the donkey punch, but even more twisted.
Shaurya: Yo I just put an air freshener in my sheets.
Me: Why would you do that?
Shaurya: So my bed smells good when I Shaurya Slap a ho tonight!
