You know George Carlin's famous seven words?* Shout them out. Scream them at the top of your lungs. If you're not quite ballsy enough for those seven, something milder is okay. Find the dirtiest word that you can comfortably say out loud and yell it. Think of it as catharsis: there's all that darkness and filth and pain inside of you, and it has to come out one way or another. This way is fast and a lot more fun than you might think.
*Shit, piss, fuck, cunt, cocksucker, motherfucker, tits.
