Uninitiated beaus hurry to give inappropriate details (9)

I believe the answer is:

overshare

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

'give inappropriate details' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'uninitiated beaus hurry' is the wordplay.
'uninitiated beaus' becomes 'overs' (I can't justify this - if you can you should believe this answer much more).
'hurry' becomes 'hare' (I've seen this in other clues).
'overs'+'hare'='OVERSHARE'

'to' is the link.

Can you help me to learn more?
