A type of endorsement (usually done by celebrities) that tricks people into thinking a celebrity is not being paid to promote or endorse a product/company. A celebrity may talk down about a company or a company may even make a publicity stunt to pay the celebrity not to promote their product/company. You think there is no endorsement deal, but in reality, you're being tricked into seeing that product/company's name.
