Flat earther

The peak of the Dunning Kruger effect in action and when logic reaches a state of nonexistence you get a flat earther.

Another way to classify them is much like quantum physics where we have quantum superposition where something can be 2 opposite things at one time in which case they are both smart and stupid but only smart at being stupid.

You see what I did there I killed them with the very thing they despise SCIENCE !!!!!

Me- you know one of the most respected and crucial equations in science is E=Mc2.
Flat earther- No it's P3=N15
Me- Hmmm nope that's what you lack sir that is still living in his mom's basement.
Flat earther- OH SHIT !!! you must be paid by Nasa.

Man Flats

Slip on shoes for men (not loafers, moccasins, or lace-less converse), generally patterned, lace-less, and are canvas or cotton topped. Man flats are commonly worn by scenesters and emos, and are a common accessory to skinny-pants. Although called man flats, man flats are also commonly found on the feet of girls and should still be referred to as man flats.

Eww, those man flats are so horrid!
