A little drunk makes suggestive gesture, being game (11)
I believe the answer is:
tiddlywinks
'being game' is the definition.
(I've seen this before)
'a little drunk makes suggestive gesture' is the wordplay.
I cannot really see how this works, but
'little' could be 'tiddly' (I've seen this before) and 'tiddly' is found within the answer.
'gesture' could be 'wink' (wink is a kind of gesture) and 'wink' is present in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tiddlywinks that I've seen before include "Game of flicking counters" , "Counter-flipping game" , "Game of flicking disks" , "Children's game" , "Game of flipping counters" .)
