Ed's out, upset, dismissed (6)
I believe the answer is:
ousted
'dismissed' is the definition.
The definition and answer can be both to do with social activities as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'ed's out upset' is the wordplay.
'upset' is an anagram indicator.
'eds'+'out'='edsout'
'edsout' is an anagram of 'OUSTED'.
Can you help me to learn more?
(Other definitions for ousted that I've seen before include "Put forcibly out of office" , "Ejected, deposed" , "Ejected or expelled" , "Put or thrust out" , "Supplanted" .)
