siter 

A beautiful girl with a super sexy body. She is super nice but at the same time she can fuck you up so be careful bro. She likes it if a boy drinks pineapple juice . She can get with anyone but won’t admit it. She has normal sized feet and likes sticking out her tounge.

Did you see siter today? She looked fine

Sistar 

Very good female friend that you have known for years. In the context of the COVID-19 and the regulations against the gathering of people from different families, it means that the person in question (the sistar) can be considered in the same family as you are. Thus, it bypasses the COVID-19 regulations and enables face-to-face meetings between all the brothar and sistar that know each other.

Police : Gathering of people from different families is presently not allowed during COVID-19, please distance yourselves
Me : I understand, but she isn't anyone, she is my sistar which allows us to meet-up despite the current crisis
Police : I see, my mistake, please proceed

inn sitter 

Somebody who runs your inn instead of you.

If you own and operate a bed and breakfast inn and want to get away for a few days, you have few options. You can shut the place down, but that’s not very sensible from a business standpoint. You could conscript friends or relatives to fill in temporarily. Or you could hire an inn sitter.

Donkey Sitter 

Someone who takes a last minute, unwanted and dumb stand in an arguement, debate or row

She's being the world's worst donkey sitter by being on Alyssa's side
