Add new command: vomit
Allow any character to lower their satiation level at will
Along the established lines of Wipe face and Clean ears, I suggest a new command: Vomit.
Main use would be to reduce satiation level.
Perhaps also allow projectile vomiting. Vomit in a direction, range 1, maybe more depending on just how bloated you are. Splash your enemies for very very small water / kinetic damage. Splash your friends, possibly turning neutrals into hostiles, possibly garnering big laughs from the townsfolk.
The purpose during normal gameplay would be to reduce satiation below bloated, in order to allow for the eating of useful corpses before they rot away. Also, if projectile vomiting is allowed, could be used to anger neutral npcs (a la Ventriloquism).
