A play on flat earther, analogous to science and evidence denier. Despite ample evidence suggesting that schools, with proper measures in place, are relatively safe spaces for children and teachers to be, the flat schooler will have a finger in their ears. With a dangerously myopic worldview, inability to comprehend nuance, and a relatively low-ish IQ (under 110, though not always), they'll insist that schools are currently "germ factories" and that children are "plague rats". When one points out that the risks of closing schools outweigh the rewards, they just might call you selfish or a sociopath. This is projection.
This variation of idiot will often be found parroting phrases such as "trust the experts" and "trust the science". Except of course, the experts and scientists who say transmission in schools is low. Including Dr. Fauci, Unicef, CDC, and more.
Flat Schooler: "Trust the experts!"
Rational person: "Including when they say transmission is low within schools, and that schools are safe?"
Flat Schooler: (cognitive dissonance activated) "They're just covering up unsafe schools!"
Rational person: *eye roll* "You're such a flat schooler"
A flat slut is somebody named Amy who has been in a terrible sexual accident and had their face smashed against a woman's extremely flat breasts. This caused her face to become as flat as a piece of paper. If you ever meet a Flat Slut, don't get too close because she will reel you in and turn you into a condescending dick who gets really annoyed when their threesome with Amy doesn't go to plan because Geraldine doesn't know how to use a vaginal condom.
Guy 1: "Ugh, I met this flat slut at college today."
Guy 2: "Ew, was she flat?"
Guy 1: "Oh yeah, flat as a rat"
