Dummy-Dumb Poo-Poo Head 

This used as an act of retaliation in an epic gamer rap battle. This can only be used once in a lifetime by the fiercest of warriors: Chuck Norris is the only know user. When used 3 bolts of lightning will erupt from the ground into the heart, brain, and anus of your opponent. This will mean you have won the epic gamer rap battle. This is an epic victory royale.

Kyle: *finishes rap*
You: You are a dummy-dumb poo-poo head!
Kyle: *gets epically clapped*
You: Epic victory royale, broski!
