Driving or in a vehicle where illegal substances are present or used.

Any toddler walking around with a dirty poop diaper.

Ridin dirty is when a man cums in a woman, and she goes through her day letting it ride with her. :)

Cheating on your significant other.

The act of a flat earther driving while operating a video camera discussing stupid ideas like flat earth to their livestream audience or in order to upload later. (See Flerf.)
Side note: Recording in a vehicle prevents their family members from hearing how stupid they are and thus leaving them homeless or without a family while the worst of the Flerfs call their vehicle home from destroying their relationships with other humans.

Being in a place more often than usual by driving in the area as if you were looking for something. Making more of a presence in that location.

To feel overly warm & fizzy after taking prescription Pain-killers, or Doogs, with fellow users and friends.
