Couple I snubbed, one of fifty in the US (11)
I believe the answer is:
connecticut
'one of fifty in the us' is the definition.
(one of 50 US states)
'couple i snubbed' is the wordplay.
'couple' becomes 'connect'.
'snubbed' becomes 'cut' (to snub something can be to cut its end off).
'connect'+'i'+'cut'='CONNECTICUT'
(Other definitions for connecticut that I've seen before include "State of NE USA" , "America" , "one of fifty" , "One of original thirteen US states" , "state of the union" .)
