One Night In Cheyrnobel

Derived from the growing trend of naming Porn movies after geographically ironic names (i.e. One Night In Paris, One Night In Chyna) One Night In Cheyrnobel stands for a sexual experience with a less-than attractive female. Cheyrnobel of course standing for the nuclear destroyed abandoned city.

Asshole male : Girl you so ugly, if you were in a porno, they'd name it one night in cheyrnobel!

squeeze one out

When you attempt to urinate or defecate due to the current convenience of a rest room and knowing that access to one will not be available for a long time there after.

(On a road trip)
"OK, we are making a rest-stop at this gas station. This is your last chance to use a rest room for 300 miles"

"I don't really have to go, but I better squeeze one out while I have the chance'
