A technique used by elf fairies in medieval story books, in which a magic powder from shredded butterfly wings was used to cause death by ejaculation. The substance turns from a creamy substance to a super glue-like substance. Combined with the rapid twisting motion, the penis essentially turns to dust.
Sir Robert was tragically lured in by the seductive elf fairy Kara, and died as a result of a perfectly executed one-handed butterfly twist. There was nothing left of his penis.
