Reverse quadruple Cthulhu position

A sex position so odd that it looks like the participants are trying to summon an ungodly monster of some sort.

Alternatively: a kink for experiencing the deep, incomprehensible horror of humanity's inconsequential and powerless position in our universe. Like a knife play kink, but with way more existential dread.

"Man, I knew she was kinky, but I would never have guessed she would want to try reverse quadruple Cthulhu position."

"I told you she was pretty intense before you started dating."

"I know, but I figured you just meant BDSM or something."
