Hog got Balls!

Take a look at the motorcycle on the left. I know the pic is kinds grainy but my cell phone camera kinda sucks. Either that or I don't have the settings adjusted properly. Anyway, the bike on the left has a pair of gonads hanging down off the back. Not sure if they belong to the driver or the rider. The driver was a guy but the rider was a rather burly looking lass. So who knows.

What is this supposed to mean. I got balls? My bike has balls? I like balls? Kinda disturbing the things people try to say with their "things" on their stuff.
