Mattie is a super mean wo-man, she is always judging other people but gets mad when she is judged. Mattie is super short and always looking for attention. She is very lazy and not very smart

Usually a nickname for a guy named matthew or a girl called matilda.
They are very chill people that dont give a flying fuck about anything but are slight attention seekers, and don't follow societal norms, they probably figured out they were gay at like 9. Matti's have heaps of friends, and most of them are of the opposite sex. A Matti overthinks things and has somehow convinced themselves that they are either very sick or none of their friends like them.
A Male Matti is always very effeminate and sassy and probably buys cheap mascara with his pocket money, A female matti has probably already enlisted in the Marines. If you meet a matti you must be friends with them and never leave them or they will beat your ass.
