Pushy, but is over getting upset (9)
I believe the answer is:
obtrusive
'pushy' is the definition.
(thesaurus)
'but is over getting upset' is the wordplay.
'getting upset' is an anagram indicator.
'but'+'is'+'over'='butisover'
'butisover' with letters rearranged gives 'OBTRUSIVE'.
(Other definitions for obtrusive that I've seen before include "Unwelcomely prominent" , "Unduly prominent" , "Annoyingly noticeable" , "limelight-loving?" , "difficult to miss" .)
