If you don't know what a 'guitar swing' is, it's when you throw your guitar around your back in the middle of a song using the strap, then you catch it when it comes back around and keep playing. And when it's done right, you look like a total stud.

But check out a video on YouTube called 'Guitar Swing Gone Wrong'. A guy tried to do it, but his strap came loose, and he accidentally launched his guitar in the air.

I don't know why, but I just can't stop laughing at this. Poor guy.
