Tornado Spin:

Tornado Spin is a Rocket League aerial control technique in which the car rotates continuously while using boost, usually by combining air roll and directional input to create a corkscrew-like motion.

It is used to keep the car adjustable in the air during aerials, ceiling plays, and recoveries, because the spinning motion can help align the nose, roof, or wheels with the ball or the ground at the right moment. Players use it to stay flexible while traveling, rather than flying in a fixed orientation. For example, a player going up for an aerial may Tornado Spin while boosting to approach the ball at an angle, then stop the rotation just before contact to hit it cleanly.
