A sudden and unsuspected proposition to either purchase direct-sale products or become a multi-level network marketing salesperson. It is usually perpetrated by a casual acquaintance under the pretense of an innocent social engagement, such as a coffee or a "party".
Joe: "Hey, weren't you meeting Chet for coffee today? How did that go?"
Frank: "It was an amwaybush. Classic execution. I didn't spot it until after I ordered. I should have suspected when he didn't seem to want anything when he called."
Joe: "Better you than me. Did you fold??"
Frank: "No, but, uh, better not answer any unknown numbers over the next couple of days."
