General
boludo
What does boludo mean?
A fool, idiot, or jerk. The source is Spanish 'boludo', literally 'having big balls', historically linked to a (likely folk) story of front-line soldiers; as an insult it means dim-witted, the opposite of clever.
"No seas boludo. (Don't be an idiot.)"
Origin
Spanish/Rioplatense slang long absorbed into porteno everyday speech and documented alongside Lunfardo by the Academia Portena del Lunfardo; the literal 'big-balled' sense is clear, but the popular soldiers-of-the-front origin story is folk etymology and unverified.
