Coyote arm is the life threatening condition which occurs after waking up next to a MOTAS discovered to be coyote ugly. Presumably, the MOTAS in question had been previously perceived as remarkably similar to Traci Lords while under the influence of controlled substances. However, when lucid consciousness is regained and the MOTAS is correctly perceived as Roseanne Barr, the subject endeavors to gnaw off the arm resting underneath the MOTAS' pillow rather than wake the MOTAS-- not unlike a coyote gnawing off its own leg to escape a steel trap. Not pretty.
