고 도다

go round and round

Every line here doubles the verb for turning, giving the phrase for something circling back to where it started. Three of them apply it to fashion, saying trends come round again, and others use it for a meme that keeps recirculating, water going round in a system, people cycling through the same places, and suspicion passing from one person to the next. The fixed pairing is what carries the meaning, not either half alone.
