A bad deal; a fraudulent business or transaction. I can't believe I spent so much on this blender, and it's already broken. What a rip-off! I heard on the news that the charity is a rip-off, so don't send them any money.

One who cons or otherwise deceives people. I wouldn't play cards against him if I were you—he has a reputation as a rip-off merchant.

A person who exploits the vulnerability of others for their own sake by manipulating and taking advantage of their confidence. Be wary of rip-off artists who send emails claiming to be a bank and asking for your online login information. He's just a small-time rip-off artist looking to con you into giving him a bit of money.
