A munt buddy is someone you go Munting with, which consists of two live people and one dead (male or female) Finding and digging up a semi-decomposed corpse, One person then goes down on said corpse whilst the other jumps on the dead persons stomach - causing the juices (decomposed organs etc.) to be forced from all orifices, These are then drank by the person orally connected to the corpse.
John: I love my muntbuddy Karkat!
Dave: i didnt know you guys went munting
