Snaking is a technique for experienced players that allows the user to continuously drift back and forth to perform Mini-Turbos on a straightaway. It was first developed as a byproduct of online competition in Mario Kart DS, though the technique has been available since Mario Kart 64.
The technique is essentially a chain of Mini-Turbos. Snaking is easily done by lighter karts with extreme handling, mainly the Egg 1, Dry Bomber, and ROB-BLS. It is easily done on Figure-8 Circuit, which is why many beginning online players don't like this course. It is generally looked down upon to use the technique against unskilled or non-snaking opponents in online matches, but it is commonly used in Time Trials to achieve impressive records.
