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.
