Video-Bombing and Photo-Bombing pretty much mean acting like an idiot behind the people in front of the camera.  Check out this little dude mocking his sister's stupid dance moves and awful taste in music.Lots of funny things in this video.  The first of which is definitely how white this chick looks when she dances.  If you're going to listen to crappy rap music, at least learn some moves from the big booty video hoes.  Secondly, I feel bad for this little dude.  I'm sure his sister did something awful to him, when she really should be reevaluating her life.
