You're a gay loser!
C'mon now! Those things are beyond out of style. however, there is this jack-ass in my gym that still wears striped spandex with his tank top tucked in and YES he has a fanny pack or fag bag (whatever you wanna call it) to go with it! Dude is about 165lbs MAX!
Bottom line is....if you're not a granola eatin', mountain climbin', backpack wearin', avid hiker, then you simply should NOT be wearing a fanny pack. Yeah, there ok if you're with your family at an amusement park for the day and you're going on rides and shit, then yeah, they come in handy. But other than that, STOP WEARING THEM!
