Night Jackal 

A name, verb, or exclamatory phrase used to denote someone or some action that qualifies as a creeper or stalker and is usually a pedophile. The term is believed to have originated from a real-life stalker-creeper who called himself the "Night Jackal" for a user name on the Internet, was caught masturbating at a local theater in the middle of a Jonas Brothers movie, and is now something of a local celebrity.

Person: Dude, you know that Rahul kid? I heard he invited a group of child trick-or-treaters inside his house and locked the door and chased them around.

Person 2: Oh man! What a night jackal!
