false advertising

1. In advertising, the act of making inaccurate claims about a product. If the ads say that a certain product is supposed to be able to do everything under the sun, it's probably false advertising. Wait, you can't claim that this machine makes ice cream if it really doesn't—that would be false advertising. Make sure the copy you write is truthful and accurate because false advertising would expose us to legal liability.

2. By extension, in online dating, the act of falsely representing oneself, typically by posting misleading pictures of oneself or otherwise making false claims about oneself. He looked nothing like his Tinder picture—it was total false advertising! Am I the only honest person on this whole dating app? I've been out with five guys, and every single one has lied in some way about their career! A: "Wait, these are pictures of a model. There's no way this is actually the girl you're talking to online!" B: "Ugh, not false advertising again."
