UNVEIL

Unveil - make something secret known; uncover; remove a veil.

e.g.

We unveiled the Revology Mustang replica to the public for the first time today at 

the Amelia Island Concours.

or

We worked hard to unveil the way some reporters were not giving complete news.

BUTTER SOMEONE UP

flatter someone to get what you want

e.g.

She's been so nice to me lately. I am sure she is trying to butter me up so she can leave early from work.

or

I'm just going to butter up the teacher – I'm sure she'll give me another

extension.”

SHAKEDOWN

Mafia uses shakedown to get information or money from the people they "protect".

- extortion through blackmail

e.g.

Officers get tipped off to a drug shipment in the prison - and now they are ready for a shakedown.
