When a person pursues a sexual encounter with another person, usually of the same gender, and backs out at the last minute. When they are about to seal the deal, they come up with any and every excuse to not complete the task. In essence, they are afraid of sex, but want to seem like a sexual deviant to the rest of the world.
Michael will Achen-back Out everytime. He acts like a player, but is terrified of actually having sex.
