Wee-wee in dribbles (6,2,6)
I believe the answer is:
little by little
'wee-wee in dribbles' is the definition.
I can't tell whether this defines the answer.
'wee-wee' is the wordplay.
I cannot quite understand how this works, but
'wee' could be 'little' (similar in meaning) and 'little' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for little by little that I've seen before include "I'm making you wait" , "Autobiography of chicken" , "It's appearing in instalments" .)
