A camper or douchebag that far surpasses the typical level of asshole behavior found in the online gaming realm. Used to describe someone who is highly despised.

Most literally, it describes one who holds magical abilities that are attuned to the art of being a complete fag.

See: fag + mancer

Dammit, that fagomancer just camps behind the boxes and makes fun of whoever he catches by surprise. Lots of skill there.
