Painfully fake looking lips. . They can always be spotted from the side. If you rolled your upper lip up and your lower lip down, glued them to you face, and covered them with matte lipstick, YOU would have Kylie Jenner lips. Congratulations.
Girl #1: OMG, I'm going to get "temporary" fillers injected into my lips so they will look like Kylie

Kylie Jenner lips.

Girl #2: Okay, whatever makes you happy. Just make sure you get a decent doctor to do it . Otherwise, they'll look lumpy and misshapen like Snooki's lips and teeth.
