That chick dates a lot of guys, she's a realcrab cart.
A small, man powered cart that sells cheap foodstuffs by the side of the road such as satay sticks, corn, dumplings, etc, that taste great when you are bladdered at 3 am, but leave you with a sore tummy and runny botty the next day. Used to be very prevalent along Legian Street in Kuta many moons ago.
Geez I'm feeling sicktoday. I've been driving the porcelain bus all morning. Wish I hadn't stopped for a chew at the cholera cart on the way back from the Kuta pub crawl last night.
An electric or gas powered buggy that doesn't go very fast but is really fun to do stunts in. They are top heavy and easy to turn over. Try driving one down a narrow, curvy, hilly trail through the woods and see if you can turn it over.
We drove my golf cart nicknamed the big greenmarshmallow down the woods and as I rounded the corner too fast, I turned it over!!!
