Baboon Butt
A baboon butt is when a guy rams his cock so hard into a woman’s butt that it turns red like a tomato that just got slapped.
My dad’s butt was so red it looked like it had been hit by a brick.
My brother’s butt was so red it was like it had been kissed by a fire engine.
My friend’s butt was so red it looked like it had been painted by a madman.
