When 2 men go ass-to-ass and shove their balls into each other's assholes.
The ballocaust? That's when Mosier shoved his balls up my ass, man.
Similar to the "O face", "Brown Face" is the uncontrolled spasming of the facial muscles due to an especially pleasant defecation. Also known as the "B face".
All that fiber made a sweet turd. I'm sure my brown face was epic as I defecated. But it was quite an experience to follow B face with ring sting.
