Re: My friend is a backstabbing fuckwit
You have three options.
1. Suck his cock and quench his thirst.
2. Fuck his mother and threaten to put a pic on Facebook about it.
3. Let him fuck your mom and quench his thirst.
In all seriousness, dump either or both of them. If they want to fuck each other that bad, man up and/or let 'em go.
