mill rat 

Cool bums who hang out on mill ave in tempe, arizona. Often these people are artists, who will make you things or preform for you if you give them attention.

Person A: Dude, Happy Cabbie made me a hat that looks like a fish out of balloons!

Person B: Dude, he's my favorite mill rat.

Mill rat 

An utterly despicable waste of space that inhabits Mill Ave., in Tempe, AZ. They pass themselves off as artists when in all reality they are no-talent-ass-clown-college-drop-outs that survive off of the donations of others nearly as retarded as they are.

The Mill Rat is sleeping in vomit.

The Mill Rat is consuming vomit.

The Mill Rat is covered in my vomit.

mill-rate

Da degree dat da state BMV and/or local assessors "put you through da processor" when deciding what da tax-percentage of da absurdly-inflated supposed resale-value of your property or vehicle is gonna be this year.

It's hardly surprising dat Maine has da highest mill-rate in da entire country --- heck, our current governor is even NAMED "Mills"!

Millrat

Young homeless people and panhandlers who congregate around Mill Avenue in downtown Tempe, Arizona. Though often used as a derogative term, it is also used by the street people to describe themselves.

Probably coined as a variant of mallrat, with "mall" replaced by Mill Avenue.

Those panhandlers aren't ASU students, dude, they're Millrats.

The Gary Millrat 

The act of servicing production workers through the washrooms glory hole with the promise that said production worker will break something so the millrat can get overtime.

Dang, old boy just bought a new motorcycle, he really must have did the Gary Millrat to be able to afford that!
