Slarmin' Hard
To do completely unproductive things (surf teh interwebs for pictures of pugs in clothes, watch an entire season of Dr. Who, eat massive amounts of chicken wangs) for excessive amounts of time, especially while in a ridiculously relaxed/possibly unhygienic state.
I'm sorry I couldn't make it to your Bar Mitzvah, Timmy, I was too busy slarmin' hard.
