Flirts (7)
I believe the answer is:
teasers
'flirts' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for teasers that I've seen before include "Tricky questions" , "Problems that are difficult to solve" , "Puzzles" , "Difficult problems or people who chaff" , "Steers a way with riddles" .)
