Nosirrah is a person that is very cool and chill. is a very nice person and very smart too. They are pretty corky and kind of nerdy. But and pretty shy once you get to know them they are a very warm a welcoming person.
Wow have you talked to that person they are really nice when you get to know them they must be a Nosirrah.
