The trash skateboard one rides on rainy days. Bearings are janky and slow, likely been wd-40d at least six times. The deck looks like a chewed up popsicle stick with griptape on it. The wheels might be bigger, old, chipped up longboard wheels that look like they rode over a bed of nails. (A person might want big wheels to compensate for the bad bearings.) The trucks could be part Independent, part Thunder, with some old bushings from a kiddie skateboard. It's the board made from odds and ends, perfect for subjecting to torture like wet pavement.
There's no way I'm walking to work today. I don't care if it's raining, I'm taking the skateboat.
Gilbert: "It's wet outside. I want to skate, but I don't want to ride my Powell Peralta."
Marty: "Dude! Take your Skateboat!"
