Sarcastic young floozie (4)
I believe the answer is:
tart
This could be a double definition.
'sarcastic' is the first definition.
(I've seen this before)
'young floozie' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for tart that I've seen before include "Sharp; pastry" , "sour type of pie" , "Acidic in taste" , "Open fruit pie" , "Open-topped pie" .)
