Kid drinks last in bottle (5)
I believe the answer is:
tease
'kid' is the definition.
(I've seen this in other clues)
'drinks last in bottle' is the wordplay.
'drinks' becomes 'teas' (tea is a kind of drink).
'last in' indicates one should take the final letters.
The last letter of 'bottle' is 'e'.
'teas'+'e'='TEASE'
(Other definitions for tease that I've seen before include "Taunt or bait" , "Irritate playfully" , "Tantalize" , "Poke fun at" , "Deride" .)
