Crown
To "crown one out" is to perform oral sex on a person(s) of the opposite sex. Usually done in a bathroom or some sort of small area or room. The word originated from the Asain culture as far back as 2014.
*two partners go into the bathroom* Man: "Hey you tryna crown one out?" Woman: "What's that even mean? It's New Years I only got with you just to get with someone on New Years."
