When you can get through a series of crunches without queebing.
I did my cooter crunches in gym today while my partner held my feet.
the female version of a tea bag. this is when a woman waits until someone is asleep and drops her "cooter" on his or her face as a form of a prank. this is quite a feat and should be praised for the creativity and execution.
Jessica cooter crunched Laura while she was asleep, we all died laughing.
