Kick-arse or Kick-ass is a simple larp mechanic used in many New Zealand theatre-style larps. Physical conflicts are resolved using paper-scissors-rock, with characters with the "kick-arse" trait automatically winning. Winning a conflict allows the winner to force a truthful answer, take an item, incapacitate the losing character for five larp minutes, or (in some games) kill the losing character. Variants include multiple levels of "kick-arse", multiple traits (e.g. physical and mental), and "kick-arse" merely winning ties.
