Racer X

Racer X is Rex Racer - Speed Racer's brother.
In the movie, he fakes his death to protect his family from harm from the big industrial racing corporation. He keeps his identity a secret not only with a mask and sunglasses, but also got a surgical "makeover" on his face to change his identity. He later on in the movie reveals his face to Speed, but Speed doesn't recognize him due to the surgery.
Since Super Smash Brothers Brawl just recently came out, you'll probably be thinking to yourself, "Damn, that guy reminds me of Captain Falcon!

As soon as Racer X stepped out of his car to help that Asian guy, I thought to myself "HOLY SHIT, it's Captain Falcon!"

Generation-X

1) The generation that was maligned by the Boomers because we are not Boomers

2) The generation that finally reintroduced good music after the horror of the late 1980s.

Me: I'm getting sick of watching VH-1. When will a Green Day video come on?

Boomer cousin: You're so Generation-X. Why don't you listen to my James Taylor CDs?

Me: I'm already bored.

X-Boy

Guys who are only looking out for themselves and not "For The Boys". Will go out of their way to rattle buddy's and inconvenience them.

Chris drove to the bar without me, such an X-Boy move.
