Stomach aches can be caused when players (foolishly) consume uncooked meat. For a short period of time, the pain within their belly causes them to lose 1-3 points of health. This condition, while not fatal at high levels, causes a continuous screen of spam.
Unfortunately, there is little one can do when facing this condition. Typing the words “shit”, “crap”, “diarghea”, “puke” and “vomit” do not affect this.
