A bacchius (/bəˈkəs/) is a metrical foot of three syllables, consisting of one unstressed syllable followed by two stressed ones.

In accentual-syllabic verse we could describe a bacchius as a foot that goes like this:

da DUM DUM

Example:

When day breaks

the fish bite

at small flies.

The Christmas carol 'No Small Wonder' by Paul Edwards is a fair example of usage.

The name is thought to come from its use in ancient Greek songs to the god Bacchus.
