Flibbertigibbet

[busker]

Absent love,
flibbertigibbet,
thy flitting is as fruitless 
as a moth’s at the moon,
as Percy Shelley
said eloquently,
and Bob’s bird whistled
on the banks of the Doon.

[TranquillityBase]

Had to work on those last two lines, but made a fortunate guess. Enjoyed it all, now to the full.
