Yapflip

Yapflip is an Unggoy mentioned by another Unggoy in a long comment that can only be heard with the IWHBYD Skull turned on. Yapflip is, apparently, Flipyap's brother. Flipyap is mentioned by Bungie for humorous purposes only (as is Nipple Academy, which refers to the food sacs Grunts use: food nipples).
