cheek peak
When a girl is wearing really short shorts and just an inch or so of ass cheek peaks out the bottom of her shorts in between strides.

Cheek peak
The slither of arse cheek peaking underneath when someone wears very high cut shorts or hot pants
Obi likes to wear hot pants to maximise his cheek peak
