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.
Example: realizing he just gave away all his lives in a Comodore64 game to his opponent, "Oh, botty stab."
