To "Snool" - as in the art of "Snooling" - is to stealthily place your penis into a sexual partner's mouth, while they are sleeping.

A "failed snool" is when the subject awakens, usually inflicting severe pain on your manhood in the process.

"Speed snooling" is a sport, where one snools as many people as possible in a set amount of time.
