Emo People Hangry

Listen up, buttercup. This joke plays on the stereotype of emo people being sad and liking to hang around (pun intended). "Hengruy" sounds like "hangry," which is a combo of hungry and angry. So, the joke is that emo peeps hang each other because they are too hangry. You probably didn't get it because you're too busy listening to My Chemical Romance and writing poetry about your feels, dummy.
