coyote arm
The coyote is one of the only animals that will chew off its own arm to get out of a trap. A human having coyote arm means that he or she is almost willing to chew off their own arm to prevent waking up the ugly mess they fell asleep next to where the mess may be lying on their arm.
Mike had a serious case of coyote arm after waking up next to that disgusting looking girl he got drunk with last night.
