For those who aren't hip to the slang Jenner's throwing around, "LB" refers to "Like Back."

When you're a lip-color guru with millions of followers, it's no surprise that people are going to try and capitalize on your fame. But if you think Kylie Jenner is going to allow it to keep happening to her, you've got another thing coming.

No word yet on how long Jenner plans to keep this up — some of those followers are legit fans, after all — but hey, at least she's taking a stand.

Godspeed, Kylie.
