a vagina infected with bacterial vaginosis, a condition also known as BV. Comining B and V sounds, you get "beav", hence "beaver".

Beavers are charaterized by a foul smell: sometimes fishy, starchy, vomit-like, yeasty, or like a bacterial pus discharge rotting smell.

Beavers are accompanied by a discharge that resembles watered down glue. Beavers are not disease carrying, yet they suggest that 1.) your girl doesnt wash her vagina right. 2.) your girl is probably fucking other guys. 3.) your girl doesnt whipe her ass right.

Personally, I enjoy a beaver on a regular basis.
most of the time i pull her panties off to fuck her, and there is some nasty BV discharge shit oozing out of her beaver. oh well.

Get the beaver mug.
Leaking orifice, such as a mouth or a vagina. From the French word bave, which means dribble.

The animal is called a beaver because of a white patch around its mouth, which resembles semen.
