mastadon claw 

a disfigured vagina wherein a long hanging meat hook sags from both vagina lips in various lengths. historians and scientists are still working to find out whether this is a mutated clitoris or just extra skin within the depths of the glory hole. one thing is certain, this abomination of the poon is the mark of a true whorebag.

"Dude, I was pulling Kyla's panties off last night, and her mastadon claw was like pow...right there in my face. It was so gross. I totally kicked that bitch to the curb...she's obviously a whore."

"My mastadon claw itches."
