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.
A person who's primary goal in life, is to have as much sex with the female gender, as humanly possible. Perpetually unattached romantically, they care nothing for the notion of descretion. Completely uninhibited in their behaviour, they will fornicate anywhere, with anyone, at anytime. Often are either revered, or despised for their qualities.
A beave is a couple that are never separated from each other and are together as much as possible. When they are together they won't mix with the others in the group and will just spend their time gazing into each others eyes. Conversations between them is often limted to "Yes...no....yes...no....YES....Noooo....mmm"
Beave couples are often so wrapped up in each other that its hard to tell whos limbs are whose. At night they are best left alone as they are probably having sex.
The longer a Beave couple stay together the more they will lose their identity. Throwing things at them has absolutely no effect.
"Omg those two are turning into Beave"
"Beave are at it again. Their hair is so similarfrom the back you can't tell who is who"
"I think Beave are having sex in the playground again. RUN!"
