Rah-rah feeling (4,6)
I believe the answer is:
team spirit
'rah-rah feeling' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for team spirit that I've seen before include "displaying camaraderie" , "Willingness to work together" , "staff bonus?" , "Morale" , "mood in the group" .)
