a mattie is a straight up slut, she’s to afraid to admit it but yet she try’s to suck off anyone she can, they are normally attracted to spooks and we like to call them a snake
a sick bastard who tells silly asians your dirty dreams and will create horribly awkward moments in front of a grocery store. A Mattie can also be related to poop
Sue- "Zomg! that bitch is a bitch!"
Karen- "Psh chya! She's such a mattie"
There are two types. The person who likes their own cousin so I call her Alabama, and steals your freaking crush and so you hate her. There is also the one that is your friend and she’s nice.
