Coarse person turning dried grass over and over (5)
I believe the answer is:
yahoo
'coarse person' is the definition.
(a yahoo is a rude or noisy person)
'turning dried grass over and over' is the wordplay.
'turning' says the letters should be written backwards.
'dried grass' becomes 'hay' (I've seen this in another clue).
'over' becomes 'o' (cricket abbreviation).
'and' is a charade indicator (letters next to each other).
'over' becomes 'o' (cricket abbreviation).
'hay' in reverse letter order is 'yah'.
'yah'+'o'+'o'='YAHOO'
(Other definitions for yahoo that I've seen before include "Lout (in Gulliver's Travels)" , "Brutish animal species from Gulliver's Travels" , "Brutal lout" , "Rude or brutish person" , "Swift brute" .)
