This is when a female is wearing low cut gym shorts and their legs are uncrossed and you are able to peep a little bit of side vag.
Short for beaver cleavage. This is sometimes hard to spot but is great when you get the right angle. I first noticed beave cleave in seventh grade gym class when the girls would do their stretches and have been trying to spot it ever since.

Where one's vagina is visible through clothing. Vaginal cleavage; "Beaver" cleavage.

"These pants give me hella beav-cleav..."
