box night 

The act of masturbating together, to porn, wearing a box on the head to avoid seeing each other. Because that would be awkward.
Might have be triggered by the ridiculous house prices in London forcing adults to share flats.

Up for a box night?
Yeh!
Bring your own box. I've just got one.

Nightmare-Box 

A username, for the internets. The most rarest of all usernames, too. Only a handful of people use this name. And people whose name is "Nightmare-Box" is most likely a bisexual, teenage, cross-dressing, male weeaboo from North America with nothing to do. A "Nightmare-Box" will use CAPS LOCK when showing affection through the internets. They have a strong obsession for YouTube, 4Chan, and Anime Conventions. They hate MySpace and love cosplaying.

Allan: Are you going to Acen 2010?
Joey: No, you?
Allan: Well, duh. I'm gonna cosplay as Sasuke.
Joey: He's stupid.
Allan: YOU'RE STUPID, STUPID.
Joey: God, you're such a Nightmare-Box.
