He gets put out when angry (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' means one lot of letters go next to another.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'put' with letters rearranged gives 'tup'.
'he'+'tup'='HET UP'
'when' is the link.
(Other definitions for het up that I've seen before include "On edge - agitated" , "Angry - excited" , "in a state" , "Irate" , "Overwrought" .)
