An expression a typical Harold McGee would use when asking his students to stop daydreaming about being a thousand miles away. Often used during important lectures.
When you're sitting there sweating bullets on the AP exam, I'm going to remember this day, how you didn't hear a word I said. You were off tubing in aruba, a thousand miles away.
When you drink wine late at nite, start feeling sentimental (maybe even start crying) and begin trolling You Tube for old songs and videos. You then go onto Facebook and start posting the You Tube videos on all your friends and ex-boyfriends Walls.
Friend: Mary Kay Mahopac, why did you post so many corny You Tube videos all over my Wall last nite?
Mary Kay: Lol Sorry, I was wine tubing. But when I woke up this morning I thought I deleted them all. I guess I forgot yours.
Friend: Well the internet called and said "Stop posting sappy videos on people's Walls"
The act of deleting one's You Tube account, usually committed in a moment of personal crisis. You Tubacide is often followed by feelings of regret, and the opening of a new account with a screen name closely associated with the You Tuber's previous screen name.
Dumdiddly committed You Tubacide, but opened a new account. His new screen name is Dumdiddlydork.
