"Like," Magnus says, and pauses, thinking. "You know when you walk into a room and you're like, 'oh gods, I just know I'm going to regret getting up this morning and coming here?' That's a feeling you get when the vibes are off. They're kind of like, I guess, an emotional resonance? Or, like energy? Something you can't really quantify or define but you know it's there. Like-- when we were helping Shen Yuan pick out his date outfit, and different things had different, like, feelings to them? Each one had its own vibe. Like the one that gave off, um, extremely horny vibes, and the one that gave off 'I'm a fine upstanding gentleman who would never think of, um, screwing on the first date' vibes. Or like, in other uses of the term... Loki is low-key kind of hot, but his vibes are atrocious. Very 'I'm extremely evil and will destroy everything you love.' And me and you, we vibe. We get along and we get each other and it's pretty easy, right? And our birthday party had great vibes. Sagramore and Laertes's wedding dance had good vibes, too, but they were a lot more intense." He twists to look at Galahad's face. "I don't know if I'm explaining this right."
