The term used when a person pours hot chocolate into a womans vagina, (if they are available, the little marshmallows are added) The man wraps the womans legs around his neck and sips at the vagina. If the woman climaxes while the man is lapping at her, this will spray the chocolate out, making Chocolate Rain.

John: Ya but when i got back to the lodge i ordered a Chocolate sougina and it got the chill right out.
The vagina of a slut, a girl/guy who's had incredible amounts of action, and therefore is a giant slut for doing so. Used to describe the type of vagina of a big ol' whore, meaning that it's been penetrated many times, or looks like it could have been.
