To be overly offended/emotional over a post/status/picture online, or over something trivial in real life. To be overly sensitive to shit that has nothing to do with you.
You don't like a post on Facebook, it really offends you, so instead of being an adult and unliking a page or moving on with your day, you become all homotional and bitch, whine and complain to everyone who will listen on said page.
