- adj. A (U.S. pejorative slang) Very ugly, nearly always applied to a non-canine female.
Folk etymology: Trappers in early America would often find a coyote foot in their traps; the coyote would be so desperate to escape they presumably chewed their own limb off. In the 1970s, a comedian may have coined the term as a method of escaping from a drunken one night stand on the morning after; chewing your own arm off if she is sleeping on it, so that you can make a quiet exit without waking her up.
