Drinking too much, perhaps, and sharing a bit? (11)

'a bit?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?

'drinking too much perhaps and sharing' is the wordplay.
I cannot really see how this works, but
'drinking' could be 'lapping' (lapping is a kind of drinking) and 'lapping' is found within the answer.
'too much' could be 'over' (over can mean to too great an extent) and 'over' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
