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.

As a noun, an een often refers to a small, perhaps impish-like person or subject that is fond of motion. This also relates to the verb form of the word.

As a verb, een refers to motion in a hilariously consistent manner. Scholars maintain that the derivation, perhaps thousands of years old, comes from the "eeening" sound produced by mopeds.
