Maybe healthy competition at first: everyone getting a buzz in the neighbourhood! (5,4)
I believe the answer is:
local call
'a buzz in the neighbourhood' is the definition.
(phonecall to somewhere near by)
'maybe healthy competition at first everyone' is the wordplay.
'maybe healthy' becomes 'local' (I am not sure about this - if you are sure you should believe this answer much more).
'at first' indicates taking the first letters.
'everyone' becomes 'all' (all people).
The first letter of 'competition' is 'c'.
'local'+'c'+'all'='LOCAL CALL'
'getting' is the link.
Can you help me to learn more?
(Other definitions for local call that I've seen before include "it's not a long distance" , "Not a long-distance phone connection" , "Communication by phone" .)
