Adjective. Used to describe
people who needlessly wear
sunglasses indoors and
carry backpacks everywhere they go, like the supermarket or a restaurant.
"I'
m carrying my
backpack into the restaurant. I'm going mattstyle."
"
Hey, would you take your sunglasses off? You're not driving on the dizogg anymore. It's bad enough going to Sprawlmart, much less with someone who insists on going mattstyle.
