snu snu [snoo-snoo]
1. Originating in Season 3 Episode 1 of Futurama, "Amazon Women in the Mood", it refers to endless sex performed on a man by a variety of women, especially by large women, usually resulting in the death of the man by crushed pelvis. It is now a popular pop culture reference and often used to refer to particularly rough intercourse, especially involving a large woman.
EX. On one hand, I've never been a big fan of coupling Wonder Woman with Superman and I'm not even always onboard with her relationship with Batman in the Justice League, but I gotta admit that Wonder Woman getting some snu snu on with Supes would be hilariously destructive and, with Batman, horribly violent and unfortunate. What do you think?
