Biting Ritual

The Biting Ritual is a supposed ceremony held by vampires to turn their victims. Marceline made up the fake ceremony in "Heat Signature". The fake version substituted pinching for biting, and ketchup for bite marks. Marceline pinched Finn and Jake's Necks, and said "Bite" and "Chomp". She then put ketchup on her fingers, and left red dots on their necks in place of blood. This fake ceremony lead to the events of "Heat Signature." She made up this ritual in order to prank Finn and Jake.
