A gathering similar to a flash mob organized through social media, where a group meets near a small business and spends about $20 each.

Somewhat related to or an outgrowth of the occupy movement.
A man that will invite you to the pub for a drink, then pretend he's being a gent by letting you through the door first. He's actually planned this before and is letting you in so you have to buy the first round. He will leave after the first round.
