look up any word, like bukkake:
To rev an engine out past the reading capabilities of it's tachometer. This often happens in built 4 cylinder engines that have been designed to rev past normal engine limits, sometimes past 11,000 RPMs. This problem is often resolved by putting a monster 5" tach on the dash. Installing this equipment is also common among ricers who want their car to seem fast.
