sigma demurely Sigmurely

lend of sigma (slang for a self-reliant, dominant, "main character" type of man, ultimately from the Greek letter sigma as repurposed in 2020s online masculinity discourse) and demurely (in a modest, reserved, understated manner; from demure, via Old French demoré "settled, composed"). The compound is deliberately oxymoronic, yoking brash self-assurance to quiet restraint. Coined by Professor Sendy.
