Absolutely loving adult party group (7)
I believe the answer is:
adoring
'absolutely loving' is the definition.
'adoring' can be an answer for 'loving' (similar in meaning). I'm unsure of the 'absolutely' bit.
'adult party group' is the wordplay.
'adult' becomes 'a' (abbreviation).
'party' becomes 'do' (do is a kind of party).
'group' becomes 'ring' (a ring is a criminal organisation).
'a'+'do'+'ring'='ADORING'
Can you help me to learn more?
(Other definitions for adoring that I've seen before include "Worshipping; admiring" , "Devoted" , "Extravagantly indulgent" , "Passionate" , "Worshipping the loved one" .)
