Reverse Polish Notation

Reverse Polish Notation not to be confused with Reverse Reverse Polish notation. It is Notation used for algebra that is easier for programers to parse. The alternative is to compute PEMDAS and that gets into abstract syntax trees. Since Reverse Polish Notation has a association with Stacks and Stack based programing paradigms it's usually found there.

Confused? If you are that's the point. Reverse polish notation was meant to be understood by people but it's still not as easy as pemdas. So that's why we use S-expressions or just pemdas.

Person A: Hey did you hear about that Reverse Polish Notation Calculator?
Person B: You living in the 1980s or something we use pemdas.

Example of Reverse polish notation:

9 2 3 + *is equvalient to (2 + 3)* 9

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."

Reverse Mr. Beast

When you show someone something really cool like a brand new Tesla or a crazy mansion, then when they express how awesome they think it is instead of giving it to them just look them dead in the eyes and say, “ok buy it”.
