crotch cleavage

The two diagonal creases leading down from a guy's hips to his crotch when he wears his pants, boxers, swimtrunks, etc. extremely low.

"Dude, that guy in the Abercrombie catalog has some major crotch cleavage!"

crotch clevage

When a male wears shorts and sits down to reveal his shorts get bunched up between his thighs, leaving what is now known as "crotch clevage."
Disclaimer: This can be a good experience, or a bad one...

"Check out that crotch clevage he has goin' on!"
