Possibly used to being thrown out (6)
I believe the answer is:
ousted
'being thrown out' is the definition.
(I've seen this before)
'possibly used to' is the wordplay.
'possibly' indicates anagramming the letters.
'used'+'to'='usedto'
'usedto' is an anagram of 'OUSTED'.
(Other definitions for ousted that I've seen before include "Put out as of office or government" , "Expelled from office or power" , "Drove or ejected from office" , "Expelled or dethroned" , "Thrown out" .)
