When a penis enters an asshole, the lack of lubricant creates a noise known as a squeakin cheek in.
One night, after Alexis having a few too many margaritas and forgetting to get the lube, James went to put it in the butt and it was an epic squeakin cheekin.
When one pretends to swallow medication, but actually hides the pills in the part of the mouth between the gum and the cheek.
Cheeking is so common on the Psych Ward that all patients must drink water after taking pills. They must also open their mouths for the nurse to inspect that no cheeking has occurred.
