Sinus and Coitus 

Sinus and Coitus are two very important functions in mathematics. The derivative (which gives the slope of a function at the point) of sinus is coitus. And the derivative of coitus is coitus interruptus, because you need to interrupt the function to measure its slope. Usually people will look at you really weird when you use those terms, because they are not used such high mathematics.

Person 1: Mathematics homeworks was really hard last night. The sinus and coitus excercises were kind of tricky, but coitus interruptus? Nah man. I went to sleep early and decided to finish coitus interruptus later
Person 2: wtf?

I swear to god, I'll fill your sinuses with urine. 

A great threat for if someone is being particularly bothersome or you want to somehow lose their contact. Let's say your ex won't stop texting you after it's been a month since you've broken up and you want to just- scare them off a little bit. Maybe even get 𝘵𝘩𝘦𝘮 to block 𝘺𝘰𝘶. This is the perfect threat for you.

Take one more step towards me and I swear to god, I'll fill your sinuses with urine.

sinurgy 

Sinurgy equals sin plus urgy. The chance to commit a sin, coupled with the urge to do so, create a kind of, well, synergy.

"All of these group sessions at the High School Cheerleading and Football Relations Conference was creating a kind of sinurgy," Dr. Bortoze noted, delicately licking away the perspiration that had somehow accumulated in the whiskers underneath his lower lip.
