Facebook Hour
The time when your friends are all online, like they're all in a group chat and they're all talking about you, even though you're not in the group chat. And it's usually between 4:00 and 5:00, like it's the best time to be online and you're the only one who isn't.
"Why are you online? It's only 4:00 PM.", Lisa
"I'm online, and no one is online. It's 4:00 PM.", Alex
"Why are you online? It's 5:00 PM, and you're still online.", Mark
