A GVB minute is an undefined amount of seconds a minute can last. The Amsterdam Public Transport Company (GVB) has the tendency to display the amount of minutes a tram or metro should arrive but one GVB minute can be five real minutes.
“Sarah at what time will you arrive? I don’t know Julia. My metro should be here within 3 GVB minutes. Oww, okay than I have some time to walk the dog.”

Cheap, easily installed, easily breakable, and somewhat tacky and gaudy vehicle modifications. It looks like a great amount of money went into modifying the car to the untrained eye. But to people who are good at spotting cheap and gaudy mods, it looks tacky.
"Hey, dude, check out Lee's car! He has chrome spinner rims, a coffee can muffler, LEDs under his chassis, chrome license plate covers, his bumper and spoiler are chrome wrapped. He also has LED valve covers, and chrome wipers!. All that rice must have cost a lot of money."
"No, Anna. That's not real rice, that's minute rice. All that stuff cost around 300$ altogether at most. Probably about $150. The rims are just wheel covers for steel wheels. You can make a custom breadboard of LEDs with a AAA battery and scrap you can find at an electronics store for less than 2$, chrome vinyl wrapping can be installed for about 10$ and the cost of a hair dryer at the thrift store, the spoiler's stock, LED valve covers, you can get at Wal Mart for 8$, the muffler was just and you can get Chrome Wipers and license plate frames at Autozone for 20$ a pair. The coffee can exhaust is just a can of Great Value coffee he stripped the paint off of , chrome vinyl wrapped, and JB Welded onto his muffler. His car's about as tacky as that gold plated crystal encrusted digital watch he always wears. Fitting, because he has minute rice on his car."
"Ha ha ha, good one!, Jair!"
