First out of bed tormented me with strop (9)

Ross

I believe the answer is:

uppermost

'first' is the definition.
(thesaurus)

'out of bed tormented me with strop' is the wordplay.
'out of bed' becomes 'up' ('up' can be a synonym of 'out of bed').
'tormented' is an anagram indicator.
'with' is a charade indicator (letters next to each other).
'me' after 'strop' is 'stropme'.
'stropme' is an anagram of 'permost'.
'up'+'permost'='UPPERMOST'

(Other definitions for uppermost that I've seen before include "Highest or most prominent" , "At or nearest to the top" , "get to top" , "Highest in place or rank" , "Support me being on top" .)

I've seen this clue in The Telegraph.
