No Rolling Stone will have such a hanger-on (4)

Ross

I believe the answer is:

moss

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

'a hanger-on' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'no rolling stone will have' is the wordplay.
I cannot really understand how this works, but
'no' could be 'o' (O resembles 0) and 'o' is present in the answer.
The remaining letters 'mss' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'such' acts as a link.
