A legendary giant or fierce warrior from medieval romances, especially Charlemagne legends; the name itself became a generic term for an overbearing bully.
From Old French 'Fierabras,' the name of a Saracen giant in the Chanson de geste cycle. The name combines 'fier' (fierce/proud) and 'bras' (arm/strength), literally meaning 'fierce-armed.'
Medieval story cycles had so much cultural impact that character names became common nouns—'fierabras' was used to call someone arrogant and bullying, much like 'Scrooge' today means a miser. This shows how literature shapes everyday language across centuries.
