You name it! (3)
I believe the answer is:
pet
'you name it' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pet that I've seen before include "Caress or fondle, as with favourite" , "Favourite, perhaps a domestic animal" , "Bad humour; darling" , "Darling; fit of sulks" , "Little darling" .)
