I’ve done a writeup about the name of blog when I started it. However recently two links came up in my Google Alerts:
The first one is from Urban Dictionary and it defines hype free as “Slang word for drug free”.
The second one is from Yahoo! Answers and states pretty much the same thing (in a conversational form).
I didn’t know this meaning of the expression until these items came on my radar recently, but they are very funny (and certainly true in more than one sense).
Update: the Yahoo Answers page states that it was deleted “according to our Community Guidelines”. Bummer.
