The act of waiting until a girl with a nice ass (or any sort of ass you like IDGAF) passes you and when that happens you follow them from behind as if you were going to your class or car. This results in a period of time of the girl's nice ass to be infront of you and you now have the ability to see it without being that suspicious.
