I see plenty of "WATS SANKING?", topics, and the like around many forums. This topic should clear up most things. If I've made a mistake or you have something to add, please post it or PM me.
What is snaking, anyways, and how do you do it?
Snaking is properly defined as a
SSMT, which stands for Short Stretch Mini Turbo. Snaking is the common term. A mini-turbo is what results when you first drift, then move the control pad back and forth until red sparks appear, then releasing R. This gives you a short boost. Now, normally, you would do this around a turn, but snaking is different, as you do it on a straight section of track. Try going down a straightaway, say, on Figure-8 Circuit. Now, drift one direction and quickly make the red sparks appear, then release, resulting in a mini-turbo. Now here is the hard part. While the turbo is going, drift the OTHER direction and repeat the process. Not everyone gets it the first, or second, time. Learning to snake just takes practice. Here is a video made by GJ_Chubz from the Nsider forum going into detail about how to snake.

Is snaking cheating, or a glitch?
You may find games that don't allow snaking. Its all your rules. Many people believe it is a glitch in the game's design, but rather, snaking has been around since Mario Kart 64. But when gameplay gets taken online, people develop and use techniques so they can win. And snaking resulted out of this. And another thing-snaking takes skill and practice, at least to snake well. A lot of people can snake on the Figure-8 Circuit, but how many can snake on Rainbow Road?
What's the history behind snaking?
As stated, snaking has been around since Mario Kart 64, but it was not totally utilized then. Snaking was first used seriously in Mario Kart: Double Dash, to get better times on time trials. When MKDS was released, it was taken online, and many figured out that snaking was a much faster way of getting around. The name was first used in MKDS (on MKDD, it was called SSMT), probably resulting from someone saying it and it going on and on. If you look when you're snaking, you go from left to right, such as a snake slithers. Properly, it would probably be called "slithering", but we all know how awkward and dumb that sounds.
So, why snake, anyways?
Essentially, if you snake fast enough to "link" your mini turbos together (making sure each boost is started during the last boost, making a constant speed boost), you are going almost as fast as someone with a mushroom. Its faster. That's what matters in Mario Kart, getting to the finish line first.
Snaking can be bad as well, especially if you aren't proficient at it. Make sure to practice enough on time trials before taking it to Wifi, or else you might hit a wall or fall off of the track.
When to snake, where to snake, who to snake with
When to snake? Wherever there is a straightaway. If you can fit in one mini turbo on a short stretch, then you will be going faster. Don't go overboard however, if you snake past a turn and miss the turn. When in doubt, kick it out. Losing one mini turbo is far better than falling off of the course.
Where to snake? Just about every level has straight stretches that you can snake on. Don't snake over uneven terrain, such as on DK Pass, or on ramps and hills, such as on Wario Stadium. When you aren't going straight over a ramp or bump, you lose speed.
Who to snake with? Its really what kart to snake with. The higher the acceleration of the kart, the longer its mini turbo will be, and the easier it is to link your mini turbos. Popular snaking carts are the Dry Bomber, the Egg 1, and the Poltergust 4000. The drift rating on a kart matters as well, as this shows how sharply you drift, or how much more you can turn during a drift. So, you can drift around tighter corners, but this has a bad effect upon snaking. Karts with a low drift rating are easier to snake with. Go try it out if you need to.
