A humorous exclamation uttered whilst playing a game, and while playing, the game characters unintentionally do something suggestive, for example, when playing Star Wars Battlefront, and you use the crawl feature and make the character back up, causing them to crawl backwards with their ass in the air. At that point, it is prudent to say "Sexy Ass!" to provide comical relief.
