The Werewolf 

Like A Gorilla Mask. You Shave Your Pubic Hair, Stash It Close By, When A Girl is On Her Knees (and You're Standing) Performing Fallatio on You, When You Give Her "The Money Shot" You Grab The Shaved Pubes With Both Hands And Throw It on The Wet Load on Your Sexual Partners Face While Yelling "A-Whooooooooooo!" (Like What A Werewolf, Wolf, Coyote, Dog, Canine sounds like, If Done Correctly She Should look like a Werewolf. Also Called A Wolfman

"Yeah, We Went To My Place, We Watched THE MONSTER SQUAD, Then I Hit That Bitch With A Werewolf Of My Own."

Him: Yeah, I'll be right out. I'm just killing the werewolf.
