In poetry and meter, describing a metrical foot that is the opposite of a bacchius, or describing verse that opposes bacchic meter.
From 'anti-' (opposite) + 'bacchic,' from Greek 'bakchios' (relating to Bacchus). Bacchic meter has a short syllable followed by two long syllables; antibacchic reverses this pattern.
Only poetry nerds really care about antibacchic meter, but ancient poets were obsessed with these syllable patterns—it's like the original version of coding with rhythm!
