Boisterously enthusiastic reunion at home initially, repeated (3-3)

I believe the answer is:

rah-rah

'boisterously enthusiastic' is the definition.
(rah-rah means showing enthusiasm)

'reunion at home initially repeated' is the wordplay.
'initially' says to take the initial letters.
'repeated' says to double the letters.
The first letters of 'reunion at home' is 'rah'.
'rah' duplicated is 'RAH-RAH'.

I've seen this clue in The Times.
