Ridin' Flerfy

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.

"Did you see the latest flat earth video?"
"Yeah...The moron was ridin' flerfy and not paying attention to the road."
