Leaned over and told you what to bet on (6)

I believe the answer is:
tipped
'leaned' is the definition.
('tip' can be a synonym of 'lean')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for tipped that I've seen before include "Predicted to be a winner" , "Given a gratuity" , "Crowned" , "Gave gratuity to or touched" , "Gave reward (to waiter)" .)
