Angry when he gets put out (3,2)
I believe the answer is:
het up
'angry' is the definition.
('het up' can be similar in meaning to 'angry')
'he gets put out' is the wordplay.
'gets' is a charade indicator (letters next to each other).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'put' with letters rearranged gives 'tup'.
'he'+'tup'='HET UP'
'when' acts as a link.
(Other definitions for het up that I've seen before include "Angry - agitated" , "Indignant" , "in a rage?" , "Angry - excited" , "On edge - agitated" .)
