A spell in the 5th edition of DnD, which allows a bard to damage a creature by insulting them.
Essentially, it's a way to kill creatures using deez-nuts jokes.
DM: The dragon is bloodied and seems like it's on its last points of health. Bard, you're up.
Party: Please, don't use Vicious Mockery...
Bard: He fat.
Dragon: dies.
The worst insult that could ever have been said. Stronger than satan and god times 10000.
Franklin: ur mom gae Jeff:ur bro a hoe
Franklin:ur granny tranny
Carl:ur mother lost her virginity in this vicinity!
Franklin and Jeff: face melts and are casted into infinite void, where they are being raped by eight year old roblox players.
