Fairy-tale meanies (5)
I believe the answer is:
ogres
'fairy-tale meanies' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ogres that I've seen before include "'Monsters, fiends (5)'" , "Gorse (anag.)" , "Beasts" , "intimidating people" , "Bugbears" .)
