Used to refer to a person who is picked up at a party or other social gathering purely for sex.
John:Did you hear? Becky was a take away at last night's party.
Kevin:Oh please. She's a take away at every party.
Mike:So are you going to the concert tonight?
Peter:Hell yeah! I'm hoping to bag a take away too.
Another way of saying take-out.
Guy: "Im kinda hungry, wanna get some take away?"
Girl: "Sure, How bout Chinese?"
