Define Lead Pipe Deal Meaning

Lead Pipe Deal
A lead pipe deal is a deal that is so good that there is no way the agreement came around consensually; the person would have never parted with the item that is the subject matter of the transaction without you having used force

"You got that 2017 BMW for $ 5,000 ?" "Yeah, dude--isn't that a great deal?" "Yeah, man--that's a lead pipe deal."
