InstaBitch

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.
