The Parisian punching couple around hooter (5)
I believe the answer is:
owlet
'hooter' is the definition.
(I know that owlet is a type of hooter)
'the parisian punching couple around' is the wordplay.
'the parisian' becomes 'le' (definite article in French).
'punching' means one lot of letters goes inside another (some letters punch a hole in others).
'couple' becomes 'two' (two people or things).
'around' says the letters should be written in reverse.
'two' reversed gives 'owt'.
'le' going within 'owt' is 'OWLET'.
(Other definitions for owlet that I've seen before include "Wise young" , "Baby bird; moth" , "Young bird of the night" , "Junior member of parliament" , "Young nocturnal bird of prey" .)
