Sitting out of one's socks 

Nuttin' in one's sock.
Usually a last resort when one does not have a condom, toilet paper or just somewhere else to blow the load. Or when the person is too fucking lazy.

"I walked in on Adam and he was sitting out of his socks watching midget porn."
"Sitting out of one's socks is fucking nasty, dude."

one-eyed spitting cobra 

It's pretty much your mom's favorite animal. Indigenous to the trousers of the mutant and bred for its skills in sex. Usually directs its venom at the eyes when agitated.

The one-eyed spitting cobra is an endangered species. Only one is known to be left in existence.
