Under Dog

When a female wears a skirt with no under garments and sits on a male's lap and the male opens his fly and sticks his erect penis into her juiced up vagina. Making it look very casual to the naked eye.

Damn yo, it looked like Mary and Chase were doing the under dog at the local Starbucks/Safeway area.

under and out

This is a hairstyle where both sides of your hair are flipped in the same direction. Thus, one side is flipped under and one side is flipped out. This style has become all the rage on the runways this year and you'll start seeing it sported left, right and centre. In fact, people have been rocking this style out since chin-length bobs have existed. Look around carefully and you might just see someone in your hometown who is way ahead of the game.

"Wow, her hair looks so good sporting the under and out."

under-cutter slutter

A man or woman who sees you working the room, getting your flirt on, and remains in the background until the precise moment when BAM!-you have used up all your slutty powers and are drained and then they move in and take it to the next level-out slutting you.

Did you see Gina jump up on the bar after I did? OMG that strip tease was straight up under-cutter slutter.
