cock in the mouth 

A derogatory term used to express one's dislike for someone. Definitely not something to be said around the family dinner table.

Fisherman's Mouth 

A mythological disease guaranteed to get you out of any event you don't want to go to. Often used by males to get out of their girlfriend's lameass plans.

Originated from Penny Arcade.

Girl: "So are you ready to go spend the day at the farmer's market?

Boy: "Sorry, I got a terrible case of Fisherman's Mouth. Seriously, you don't want this shit."

mumra mouth

when a female takes a money shot in the mouth and then opens her mouth to allow the slimy debris to make strings of skeet connecting to both the top and bottom teeth. (resembling the thick spit in Mumra from the Thundercats mouth when he would scream "ancient spirits of evil")

I gave that chickenhead a serious dose of mumra mouth last night...
