The Dirty Side 

A term used by over-the-road truckers referring to the east coast of the United States, with its large congested cities, pollution, crime, and grime, as contrasted to the western United States with its wide open spaces, natural beauty and clean air.

I was glad to get back to the West after spending two weeks on the Dirty Side.

Dirty Side Of The Bed 

When you run off a batch before going to sleep —letting it fly and land where it may— and then roll over to sleep in the clean part of the bed.

You act nonplussed when I told you about my Dirty Side Of The Bed, like you've never laid in your own filth before.

North Side of the Dirty South 

Generally the state that is just south of the Mason-Dixon line. Maryland and some will also consider Washington DC.

We about to take on a ride through the north side of the dirty south!

Right side of the dirt

Alive. Not dead and buried.

Tom: I had a very bad car accident last week. Busted my leg.
Jill: At least you wound up on the right side of the dirt.
