An instant bitch. Calm, cool, cute, and collected at first, but say one wrong word and it's INSTA-BITCH!
-Geez Glyde, stop being such an insta-bitch.
-You. Shut up. And get out of my house!

A person on Instagram who is only interested in their own follower gain. Usually narcissistic teenage girls who secretly think they'll be the next Kylie Jenner.
Jane: I'm gonna follow this fake whore so she'll follow me, then I'll unfollow her and hope that dumb bitch doesn't find out.

Jane is the example of an Instabitch.
