An "adventure" normally taken by bored teenagers who are stuck in a large shopping area/town with little or no money and have nothing better to do than document it. They often use shopping carts and while a few ride in the carts and a few steer they create chaos everywhere they go, normally with a camera taking it all in.
Usually, while they're obnoxious, they are not illegal. They will buy random things such as kid's toys and energy drinks to just create something that resembles fun. In the end, it is kind of fun in the well-we-have-stories-now way.
"Dude, we were stuck at that plaza downtown and went on a 4-hour parking lot adventure."
"Really? Man, I wish I was there. I was stuck at home."
