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

If this is the answer, I'm afraid I cannot explain it.

(Other definitions for tad that I've seen before include "(A) bit, touch" , "little boy" , "Small bit" , "Slight amount" , "A small amount (colloq.)" .)

I've seen this clue in the Evening Standard.
