Little scrap flounced outside (5)
I believe the answer is:
ounce
'little' is the definition.
(thesaurus)
'scrap flounced outside' is the wordplay.
'outside' indicates the answer is hidden within the clue (a word is around or outside the answer).
'OUNCE' can be found hidden inside 'scrap flounced'.
(Other definitions for ounce that I've seen before include "Carnivore" , "Oz" , "One-sixteenth of pound" , "There are quite a few in the pound" , "Unit equal to about 28 grams" .)
