When you and your bro need to share a seat designed for one ass and you both agree to split the difference with your two asses and half-cheek it.

In the most basic half-cheeking form, both you and your bro will have one leg planted on the floor for support and the opposite cheek on the seat.
“Yo man, I just saw you from across the pool hall half-cheeking that chair with your bro. Y’all must be pretty close…”

A fart (usually in public) tried to be kept silent, by leaning to one side, and squeezing the butt cheeks together. However, failing to be silent, but instead of being a full blown butt trumpet, turns out to be a long winded high pitched squeak. Also causing it to be WAY funnier/more embarassing.
*Dude, Tom leaned over in class today and totally let out a half-cheek-squeak. It sounded like someone opening a balloon!*

Skinheads and people with skin hair cuts who understand a buoyancy of life well enough to know the ultimate fundamental of any existence since weight is burden that has been overcome. The reference is derived from a whooty, her ass cheeks, which half of it looks exactly like the back of a skinheads head and someone with a skin hair cut.
Example 1: Than man is so straight, he an heterosexual everyone calls him a half ass cheek.
