Uni 

A person whose gender is not stable and changes with time.

Or

Person who can be male and female according to time.

He told me that he was he, but yesterday he became she, which made me realise that he is actually she. Such a uni.

Uni 

Uni, term coined by me for the people whose gender is not stable and changes according to time and situation, and also there behaviour is strange.

P1: Hey, you know what, the person you are chating with is not actually a she, maybe it's a he talking like she.

P2: Fuk this, Unis everywhere

Uni 

That one person's online nickname who always makes them selves seem extremely stupid. They somehow forget both how English works and basic logic simultaneously.

That person is such an Uni, they said the revolutionary war was in 1920!
