The act of slipping a thumb into the anus during doggy style sex. Which produces a raven-like screech from the recipient.
I was totally doing a chick doggy when i dropped the Raven's claw, and she did not like that at all. There was much screaming and shot gun type buck shot pooping into my belly button.
When you and a girl/guy lay on the floor facing each other and the other person reaches there feet around your penis and gives you head.
Did you hook up with rachel last night? Did I? she gave me the meanest "raven's claw" you've ever seen!
