At the climax of sexual intercourse pretend that you're going to aim for the mouth when depositing your load, but instead hit em in the eye and say "more than meets the eye." Then proceed to "roll out!" As an option, you can choose to wear a transformer mask w/ voice changer.
My ex-girlfriend is pissed that I gave her a decepticon. Now she has a lazy eye. I had to roll out fast.

A woman who looks very attractive from behind, but when she turns around she's disappointingly ugly.

A decepticon can also refer to an older women who dresses much younger than she should in order to trick men into checking her out. This method of deception only works at a distance.
