Ketapiller
Something you become once you've had too much ketamine and you think it's a good idea to play the game caterpillers (all players in sleeping bags, kneel up in a circle and knock into each other, attempting to take each other out).
Glade festival 2008, in the healing area. It was deemed a good idea to play caterpillers whilst very floppy on ketamine - henceforth, Ketapillers were born.
