boa

I'm a little stuck... Click here to teach me more about this clue!

'wrap' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for boa that I've seen before include "native American" , "feathers around the neck?" , "Non-venomous snake" , "Python" , "Feathered neckwear - snake" .)

I've seen this clue in The Times.
