unhip

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

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

'local one in' is the wordplay.
'local one' becomes 'un' (I've seen this in other clues. I am not sure about the 'local' bit.).
'in' becomes 'hip' (both can mean fashionable).
'un'+'hip'='UNHIP'

Can you help me to learn more?

(Other definitions for unhip that I've seen before include "uncool" , "Not cool" , "square" .)

I've seen this clue in The Telegraph.
