Flathair 

Derogatory word for overly pretentious, non-self-aware germans on the internet. Originating from the description of young and sheltered, usually upper-middle-class german women acting in a naive all-knowing manner berating others while acting in ways usually mocked by the general public, and their usually purposefully very flat laying hairstyle. Has since expanded to a catch-all term including all behavior of specifically ethnic germans that are mocked upon in the general environment of the internet, but which are common in niche german-speaking communities, usually immediately identifying germans acting as if they are not a german in a more international community and the misinformation they have been spreading in their know-it-all-manner alongside it as part of that. Often ends with insults directed to those calling them out, often featuring more openly hostile displays of extremely racist and generally right-wing nationalist tendencies in direct contrast with their supposedly progressive, worldly persona.

While the literal german translation of "Flachhaar" has seen some adoption in german communities, which often make a big deal of translating every single piece of foreign vocabulary even if it is already widely adopted in regular conversation, the sheer existence of people and words not honoring the perceived superiority of humble Germany is still met with a higher than usual level of hostility, and usually world-shattering for those very sheltered individuals.

Of course it was a flathair all along, don't you have anything better to do than to insult and berate us about our own customs?
