One Direction

Another one of those crappy pop bands with all boys. While guys think they look gay, girls, for some reason love their looks. Their music, like most music today, is low quality crap that dominates the airwaves. Luckily, they will be forgotten in a year or two, and replaced by other mainstream crap.

Who's One Direction? Must be another one of those terrible bands that teenage girls love. When will music be good again?

One liner

To verbally rip someone apart using only a phrase or sentence.

That guy though he was the shit til I dropped a little one liner on him infront of his girl.

Xbox One

This thing will be a failure. It requires you to connect to the Internet once every 24 hours in order to play games. Kinect is required for it to work. You have to pay a fee to play used games. Games have to be installed in order to play and it has a hard drive that holds a mere 500 GB. It was officially announced in a live stream on May 21st, 2013.

I was going to buy the new Xbox, but I changed my mind when I saw the Xbox One announcement.
