A person who believes that the earth is flat.

Flerf's are literally the dumbest people on the planet.

Flerf 

A person who is incapable of incorporating evidence or reasoning which either falsifies the flat-earth conjecture or validates the conventional model; a flat earth believer.

I showed him photographs of the New Orleans Causeway curving over the horizon, but the flerf called them fake.

flerf 

The name for cotton remnants that become wedged in your anal crevasse after wearing boxer shorts, or some other sort of undergarment.

Bob: "Why are you taking so long in there? I gots to make some clay!"
Jeff: " I'll be another few minutes, my Joe Boxers left a 10-footer of flerf in my ass!"
