Germany Defeats Brazil 7-1 in the 2014 World Cup Semifinal
I don't know a whole lot about soccer, but I'm pretty sure a 7-1 score is a big time blowout. Especially when you are the host country, and I know Brazil lost two of their best players, but come on 7-1... really! Brazil didn't even show up for this game. The loss was so bad that the Germans apologized to the host nation for beating up on their team so bad. Not only did Brazil embarass themselves, but they brought embarassament upon their whole country.

I wasn't alive for this beat down, but when you look at the score and the stats, it's a very embarrassing loss. It still stands as the biggest margin of defeat in NFL history.

The Texas Rangers Defeat the Baltimore Orioles 30-3 in a MLB Game in 2007
Do I really need to explain why I chose this game, the Rangers won 30-3. How do you give up 30 runs in a game, you had two players that drove in 7 runs by themselves, that means that one players RBI total was more than the entire Baltimore team put up... now that's embarrassing.
