The Kylie Jenner Lip Challenge emerged in 2015 as a viral internet trend where teenagers used shot glasses or small jars to create a vacuum around their lips, hoping to mimic Kylie Jenner's plump pout. The trend quickly became a meme due to the disastrous and often painful results, including severe bruising and swelling. It serves as a cautionary tale of social media influence and is primarily used to highlight 'expectation vs. reality' scenarios, beauty standard absurdity, or generally poor decision-making. The meme remains a staple for reacting to over-the-top cosmetic trends or ill-advised DIY projects.
