Friendliest mum itches to play (9)

Ross

I believe the answer is:

chummiest

'friendliest' is the definition.
('chummy' can be similar in meaning to 'friendly')

'mum itches to play' is the wordplay.
'to play' is an anagram indicator.
'mum'+'itches'='mumitches'
'mumitches' anagrammed gives 'CHUMMIEST'.
