A man beaver is a male anus.

I know Andy says he is not gay, but last night he let some dude put it in his manbeaver

meanbeater

A person that enjoys and regularly masturbates forcefully. Often the penis feels as if the beater is angry at it.

Donny seems quiet and nice but he is a total meanbeater and takes it all out on his johnson.

manbeaver 

The mass of pubic hair around a man's genitals making it look like a woman's unshaved vagina beaver.

His balls are so hairy he's almost got a carpet. He's a manbeaver.
