I believe the answer is:

gamin

I'm a little stuck... Click here to teach me more about this clue!

'the kid' is the definition.
(gamin is a kind of kid)

I can't explain the remainder of the clue.

(Other definitions for gamin that I've seen before include "Street urchin or impudent child" , "Little urchin" , "Waif" , "Street kid" , "Little devil" .)

I've seen this clue in the Evening Standard.
