Take off after sign of approval — lounge finally is carpeted (6,3)
I believe the answer is:
ticked off
'is carpeted' is the definition.
(both can mean angrily reprimanded)
'take off after sign of approval lounge finally' is the wordplay.
'take off' becomes 'doff' (as in to doff one's hat).
'after' means one lot of letters go next to another.
'sign of approval' becomes 'tick' (I've seen this before).
'finally' indicates one should take the final letters.
The last letter of 'lounge' is 'e'.
'tick'+'e'='ticke'
'doff' after 'ticke' is 'TICKED OFF'.
(Other definitions for ticked off that I've seen before include "Reprimanded" , "Marked present" , "dressed down" , "Scolded" , "Cross" .)
