Roll the bidis! Roll the bidis! Roll the bidis...oh!

This line, repeated thrice, is a simple, direct call to 'Roll bidis!' Bidis are small, hand-rolled cigarettes popular in South Asia, made from tobacco wrapped in a tendu leaf. The repetition creates a rhythmic, almost chant-like quality. It could be a literal call to workers in a bidi-making craft, or a street vendor's cry. In the context of a Bengali Baul song, as indicated, it likely sets an earthy, everyday scene, perhaps using the act of bidi-rolling as a metaphor for a mundane task that connects to deeper spiritual contemplation, or simply evoking the simple life of common folk.
