To schmooze means to talk in a friendly way, especially to get something you want.
Schmoozing can make people think of being smooth, friendly, and maybe a little sneaky.
Examples:
He schmoozed with the boss to get a raise.
She schmoozed her way into the party.
We schmoozed with the neighbors at the barbecue.
The cat schmoozed its way into getting extra treats.
The politician schmoozed with the voters to get their support.
The salesperson schmoozed the customer into buying the expensive watch.
