That one kid at a school that can only complain about everyone and can never take a joke so when ever you say something sarcastic around them they take massive amounts of offence for no reason whatsoever. also this type of Nyah has a younger sibling with a mental disadvantage however she then will proceed to name and shame other people for things that they did not do and also call them retards being hurtful towards the younger sibling of theirs. also Nyahs of this sort are known to have patchy red hair dye and also think that they are the upmost powerful compared to every other person on the planet.
Oi, so my name is Nyah and i have rate patchy hair dye and i think i am allowed to do what i like to people cos i am a stroppy girl and no one can stop me because i have to put up with a mentally challenged sibling that i don't actually care about.
