Dang, did you see him land his butterfly twist?!
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.
