The Nussy, or the β€œnose pussy”, if you will, was discovered during the corona virus pandemic of 2020. People that had to be tested for Covid-19 had to have their nose swabbed right where the brain connects, which often led to people rolling back their eyes and gagging.

A nose-swab-fetish developed from this, because we, as humans, ruin everything.
β€œOh fuck yeah, swab my nussy”

Sir, please, I went to medical school

The most commonly found aftermarket cat-back exhaust system found on motor vehicles, especially domestic trucks and suv's. Generally popular for their relatively affordable price, large tip diameter, and loudass sound, they are one of the best selling exhaust systems to date. Although restrictive in design, most people think that the vehicles whom are equipped with such product is faster because they are fucking dumbshits when really it just chambers the exhuast flow to attain a certain frequency of sound that is relatively annoying and increases interior resonance. If you would like to be original with the sound of your car, don't buy a flowmaster. Flowmaster comes in several models, all of which suck my ass.
Dumbass: "hey did you hear that truck with the flows on it, it was fucking sick."

Me: "Fuck Flowmaster, they can kiss my ass."
