a mattie is a straight upslut, 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.
