Facebook Insomnia 

When you can't sleep, so you patrol your Facebook News Feed for new entries to comment on, or reload your page over and over again in the hopes that someone has commented on your feed, thus dignifying your existence on Facebook at four in the morning.

Roger: Seriously, I had the worst case of Facebook Insomnia last night.

John: Did you end up finding anyone to talk to?

Roger: Not really. Katie was on, and I commented on her feed, but she never kept it going. Then later, I found out that she was still online, but ignoring me.

John: Bitch...

Roger: I know, right? We're like kindred spirits...

Facebook Insomniac Effect 

When you're up late at night and you posts on Facebook instantly when they're posted. Essentially it's where the later you stay up, the less people post. Anything after Midnight tends to be Pages posting stupid stuff, but none of your friends actually post interesting content. So when something comes along that's actually cool, or in rare instances like when your friends actually tag you in a post or comment on your status, you get really excited and respond fast. It's a bit like a bell curve, during the day when you get a lot of notifications you're kinda like eh, whatever, and you're barely excited, but the later it gets the more exciting it gets....

It was around 4am when the Facebook Insomniac Effect happened: I was tagged in a video and I found myself bursting into flames, flames of excitement.
