Loosely translated from Japanese, it means, "Hurricane Kick". Those who study the Shatokan Karate style can perform it. The martial artist who uses the technique kicks off of the ground and spins with one leg perpendicular to the rest of the body. The spinning motion, when making contact, will repeatedly hit the fighter's opponent. Different fighter perform it slightly differently. Some hit more times than others while some can soar much farther with it. Akuma is the only fighter to master the Tatsu-maki Senpu-kyaku, for only he can go great distances and hit hit opponent a maximum of 5 times. Ken does not go very far, but he can hit 5 times. Ryu goes very far, but can only hit 3 times. Other characters that can perform the move or a similar move are: Sakura, Guy, Dan Hibiki, and Chun-Li Xiang (actually called the Spining Bird Kick, it is basically an upside-down hurricane kick)
The Tatsu-maki Senpu-Kyaku can hover over Fireball and Hadoken blast in later Street Fighter games, but in the earlier days, it would be stopped mid-flight by any projectile.
It is performed by making a quarter circle motion on the controller, moving from down to away from the opponent. At the end of that motion, press kick.
Oh a Hadoken eh? Well, I'll just sail over it and pummel you in the face repeatedly with my Tatsu-maki Senpu-kyaku. And if you're lucky, I might even have enough energy to unleash the uber-devastating, Shinku Tatsu-maki Senpu-kyaku. You'll be KOed like no other. WORD!
A hurricane-like kick performed by most shotos in the Street Fighter series.
I beat that guy with a Tatsumuki Senpuu Kyaku!
