A foolish or stupid person; a blockhead or simpleton.
From Irish Gaelic gomeara or gomarach (fool, foolish); possibly related to Irish gomán (idiot); entered English through Irish English dialects, particularly in the 19th century.
Gomeral captures the Irish genius for insults—it's more musical and less harsh than 'idiot,' making fun of someone feel almost like a compliment in the right accent.
