Gay men have "fag-hags" and "skirts", lesbians have their "beards". A beaver tail is the straight girl friend of a lesbian. Beaver tails often can be found out dancing at gay bars, watching movies, and just hanging out with their lesbian friends.
Lesbians love their beaver tails, especially when they are attractive.

The other night, I took my beaver tail out dancing; she had a great time!

A person performing a sexual act involving an uncircumcised male and a partner with a particularly hairy anus.

The partner may be either male or female as long as the prerequisite of having sufficient hair around the anus is met.

The person acting as the Canadian Beaver Tail approaches the partner from behind with the foreskin retracted, making contact between the anus and the exposed glans. Once contact is established the foreskin is once again pulled over the head of the penis fusing both individuals together.

"Hey, I think that anonymous human #1 passed out in the bathroom."
"Yup, looks like it's time for a Canadian Beaver Tail" *anonymous human #2 proceeds to mount anonymous human #1 in the aforementioned fashion and becomes the Canadian Beaver Tail*
