Really pointless meeting? (5)

Ross

I believe the answer is:

rally

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

'meeting?' is the definition.
(I have seen 'Mass meeting ' mean 'rally' so perhaps 'meeting' could also mean 'rally')

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for rally that I've seen before include "exchange over the Net?" , "Mass meeting -- revive" , "Call to arms - series of strokes" , "recovery" , "Regain health" .)
