When firing a gun for extended periods of time, the barrel becomes so hot that rounds in the chamber ignite from the ambient heat instead of from the firing pin striking the primer. Cook offs are dangerous because they rarely occur immediately after loading the round and because it's impossible to tell when or if it will happen.
My AR-15 barrel was smoking half-way through the torture test, so I dipped it in water to avoid any potential ammunition cook offs.

A sexual maneuver in which three males each take a shit, and give them to a single female as a gift. She then tastes all three of the specimens. The person's shit she likes best she has sex with, next best she gives a blow job too, and the unlucky loser has to finish the rest of the shit.
Man, Eric sure got the wrong end of the chili cook off last night.
