Jan 15 Word of the Day
The Nussy, or the “nose 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.
“Oh fuck yeah, swab my nussy”

Sir, please, I went to medical school
