grunge it 

v. To sleep in your clothes and wear them again the next day.

Boss: Johnson, you've been wearing that flannel shirt and those corduroy jeans for two days straight! What gives?
Johnson: I've just been too lazy to do laundry anymore. I decided to grunge it.

grungy funkin’ it 

Something you do when you go out into the world, usually with tight friends, not giving a rat’s ass how you are perceived visually or olfactorily because you are just that incredibly cool.

An intentional bastardization of the actual Macklemore and Lewis term sounding much like “grungy funkin’ it” in their hella tight anthem to thrift shopping called “Thrift Shop.”
