Group liking each other in social media — it may turn out badly (6,10,7)

I believe the answer is:
mutual admiration society
'group liking each other in social media it may turn out badly' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'social media it may turn out badly' is the wordplay.
'badly' indicates anagramming the letters (letters in the wrong order).
'social'+'media'+'it'+'may'+'turn'+'out'='socialmediaitmayturnout'
'socialmediaitmayturnout' with letters rearranged gives 'MUTUAL ADMIRATION SOCIETY'.
Can you help me to learn more?
(Other definitions for mutual admiration society that I've seen before include "Group of back-slapping friends" , "group doing promotion of its own" .)
