Town to twerps - 'get knotted (8)

I believe the answer is:

westport

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

''get knotted' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'town to twerps' is the wordplay.
'to twerps' can be anagrammed to 'WESTPORT'.
However, I'm not sure how this is indicated.

Can you help me to learn more?

I've seen this clue in The Irish Times.
