niche

Niche is used to describe a situation, experience, person etc that’s oddly specific. Often used when a person describes a multitude of things that are specific and not relatable but the statement is phrased like the person will relate.

Girl ; I hate guys that a 5 yet act like a 10, that are only 5’8 , got a small dick are named Jonathan…

Boy: That’s so niche , I’m pretty sure you just described your ex.
