What about male sheep getting agitated? (3,2)
I believe the answer is:
het up
'agitated?' is the definition.
(het up means agitated or upset)
'what about male sheep getting' is the wordplay.
'what' becomes 'eh' (sound used to ask 'what?' or 'pardon?').
'about' says the letters should be written backwards.
'male sheep' becomes 'tup' (I've seen this in another clue).
'getting' means one lot of letters go next to another.
'eh' written backwards gives 'he'.
'he'+'tup'='HET UP'
(Other definitions for het up that I've seen before include "Indignant" , "On edge - agitated" , "Overwrought" , "in a rage?" , "in a state" .)
