The story
- Spanish · derived fromjodido“fucked, difficult, annoying”
- English todayhodad
Originally Californian surfer slang from the 1960s. Perhaps from the greeting Ho! Dad, though no evidence for this derivation is known. The suggestion that it derives from Western Hemisphere Spanish jodido (“fucked, difficult, annoying”) similarly lacks evidence; also the vowel change from -did to -dad is unexplained.
