This is when a girl has dirty panties on while wearing a skirt. She could be wearing a short or long skirt, it could be revealing as well, the key is the state of the underwear that she would be wearing.

In the computer industry, the term "ridin' dirty" is used to describe a computer that's behaving erratically or running slowly due to excessive software and/or spyware on the system. Frequently, these systems must be rebooted or reinstalled.
It was taking my system like 10 minutes to boot up. Turns out it was ridin' dirty because when I removed some programs from the startup folder, it came up real quick.
