Botty stab : a polite version of "fucked up the ass" used around impressionable youngsters. Typically used for a less grievous situation than an actual FUTA moment, for instance, a mere metaphorical tickle on the
butt. Also, most often announced by the person kicking themselves in the ass. Ideally the impressionable youngster will not know the full meaning, and will
forever remain ignorant of this etymology until they read this Urban
Dictionary entry (or a plagiarized version thereof) . Coined around 1980 by a New Zealander living in Churton Park, Wellington.
