Etymology

Origin of flake¹

First recorded in 1350–1400; (noun) Middle English; akin to Old English flac- in flacox “flying (said of arrows),” Old Norse flakka “to rove, wander,” Middle Dutch vlacken “to flutter”; flake ¹ def. 4 by back formation from flaky, in sense “eccentric, odd”; (verb) late Middle English: “to fall in flakes,” derivative of the noun

Origin of flake²

First recorded in 1300–50; Middle English flake, fleke, from Old Norse flaki, fleki “bridge, hurdle”

Origin of flake³

First recorded in 1620–30; apparently variant of fake ²

Origin of flake⁴

First recorded in 1935–40; perhaps expressive variant of flag ³; compare British dialect flack “to hang loosely, flap”

Explanation

A flake is a tiny piece of something. A flake could be a tasty morsel like a croissant flake, or a not so tasty morsel — like a dandruff flake. Ewww. In some places, you can see flakes of mica, a shiny glimmering mineral, lining the banks of a pond or paths through the woods. There are also croissant flakes, dandruff flakes, and of course snow flakes, individual snow crystals. When something flakes, it comes off in tiny flecks: "The paint had started to flake off the kitchen wall." If someone calls you a flake, they basically mean you're a weirdo.
