paranasal tubercular sinus oyster

A pavement oyster not yet deposited. i.e. Still in production.

"I must be dehydrated or maybe I've got a cold coming on. I feel like I've got a big lump of chewing gum stuck up my nose. Cover your ears for a second, lads. I'm going to have a good old grockle and see if I can expel this paranasal tubercular sinus oyster."

Sinusoidal

When someone is moody or in a mood usually due to a lack of sex or not having a regular masturbating schedule in place. Derived from the fact that the sine wave traverses up and down like the mood of a bipolar bitch.

‘Yo Amelia, you’re so sinusoidal today’
‘Fuck off, I didn’t get rattled last night’
‘Oh, that explains it then’

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.
