My angry outburst about second glutton (9)
I believe the answer is:
cormorant
'glutton' is the definition.
(I've seen this before)
'my angry outburst about second' is the wordplay.
'my' becomes 'cor' (I've seen this in other clues).
'angry outburst' becomes 'rant' (I've seen this before).
'about' means one lot of letters go next to another.
'second' becomes 'mo' (both are short periods of time).
'rant' put after 'mo' is 'morant'.
'cor'+'morant'='CORMORANT'
(Other definitions for cormorant that I've seen before include "Black/white fish eater" , "Large, long-necked seabird" , "Large diving bird" , "Aquatic bird" , "Glutton" .)
