XB is an upcoming spin off of the popular term XD. As the original resembles a happy face, this one resembles a hill-billy.
XB is to be used when somebody says something funny. It can also be used to replace :"XD, XP, :), lol, rofl, roflmao, lmao, lmfao...etc", as a synonym.

The ugly Scion brand concept knockoff of the Honda Element. This boxy vehicle was marketed to a target audience of high school boys who typically cannot afford to purchase a more expensive and better quality vehicle like a Honda Element. For unexplained reasons, it is quickly becoming a favorite vehicle among bros who are giving up their fuel inefficient bro trucks due to high gas prices. Scion provides fairly numerous accessory kits, but all the owners tend to buy the exact same ones, failing to individualize their vehicles. Because so many kits are available, most owners never install true "custom" modifications.
