Addiction to watching YouTube videos.
Dan: "Hey man, last night I didn't study at all dude. I started getting addicted to YouTube videos and kept watching one after the other. You know, I've decided what I want to do know for fun and possibly as a career: I want to watch all of the YouTube videos that exist."
Adam: "Sounds like you caught the youtubelotitis bug. But really- are you serious? Are you kidding me? Sorry dude, but honestly, that's impossible. At last count there were over 50,000,000 videos on that site. Even IF you really wanted to, you would never be able to watch all of them. Sorry, dude. And in any case - do you really wanna watch 10,000 Chris Crocker-type videos and their responses and about 20,000 videos of pre-teen girls talking about themselves?"
