A cock-strap is a leather strap that a guy puts around his cock & balls to keep his nuts from receding, thereby prolonging the time it takes to have a cumgasm. It also makes a guy's dick rock-hard.
An extremely hot chick with a very unkempt vagina. Much like a venus flytrap, she lures in her victims with attractive looks, only to horrify them with an agonizingly nasty cunt.

Dave: "Eww man, you know you get that from eating yeast-infected pussy, right?"
Mark: "...she did taste pretty nasty.... BUT SHE WAS SO HOT!!!"
Dave: "Total venus cocktrap"
