Jailbait Mirage
An event that occurs when a legal adult male views a girl from afar who appears to be very attractive due to clothing choice or physical development, but upon closer inspection discovers that she is clearly underage.
John was driving past the local park, where he saw a girl in a short skirt who looked rather attractive. Seconds later, he saw her from a closer distance and realized she was 13, blaming this event on "Jailbait Mirage."
