Death by snu snu comes from Futurama, the animated science fiction comedy created by Matt Groening, in the episode Amazon Women in the Mood, first broadcast in 2001. In the story, Fry, Bender and Zapp are captured by giant Amazonian women who sentence men to death by snu snu, a euphemism the show leaves deliberately vague. The phrase escaped the episode through clips, reaction videos and meme edits, becoming shorthand online for being overwhelmed by affection or desire. Its staying power comes from that instantly recognisable Futurama absurdity.
