Kid getting a French tattoo is a poser (9)
I believe the answer is:
conundrum
'a poser' is the definition.
(I've seen this before)
'kid getting a french tattoo' is the wordplay.
'kid getting' becomes 'con' (I can't explain this - if you can you should give a lot more credence to this answer).
'a french' becomes 'un' ('a' in French).
'tattoo' becomes 'drum'.
'con'+'un'+'drum'='CONUNDRUM'
'is' is the link.
(Other definitions for conundrum that I've seen before include "anagram" , "That's puzzling" , "Puzzling question" , "Difficult problem" , "Puzzle, riddle" .)
