A very large turd that due to it's sheer size causes it to take a curved shape in the toilet bowl, hence Corvex
Jeez, I walked into the stall at Arby's and someone left a Corvex the size of a python in there! 100% Nightmare fuel!
A slang term for feces most commonly said in Texas.
I ate 2 Taco Bell x-large bean burritos and had a massive Corvex an hour later
