Today: ツルツル (tsuru-tsuru) describes surfaces which both appear to be, and actually are, smooth, slippery, and the like. Icy winter roads are tsuru-tsuru. Worn-out tires are tsuru-tsuru. Waxed floors, billiard balls, ramen noodles and Hobbs’/Dom’s heads are all tsuru-tsuru.
Today: ゼロヨン. Comprised of ゼロ（zeh-ro: Zero) and ヨン (yohn: Four), short for a 0-400m drag race. 400 meters calculates to 1,312 feet, so it’s slightly less than the actual quarter-mile (1,320 feet). However, since Japan utilizes the metric system for units of measurement, they refer to the quarter mile as the 0-400 …similar to how Metric France refers to the Quarter Pounder w/ Cheese as the Royale w/ Cheese.
