A person from Gascony in France, or someone known for boastful exaggeration and braggadocio.
From Gascony (Gascogne in French), a historical region in southwestern France. Medieval stereotypes portrayed Gascons as proud boasters, leading the term to mean 'braggart' in English by the 16th century.
Medieval Europeans had regional stereotypes just like people do today—Gascons got a reputation as boastful showoffs, probably from their proud warrior culture, and the stereotype stuck so well it became an English personality type!
