A term used to describe the rare occasion when someone decides to drop their oh-so-ironic facade and speak from the heart. It's a moment of vulnerability that's sure to make everyone uncomfortable, so use it sparingly. It's also a great way to show people that you have emotions too, even if you're too cool to admit it. But seriously, don't overdo it - you don't want to ruin your hipster cred.
I non-unironically believe that the earth is flat and that the moon landing was faked. It's just common sense, really.
