A dance/aerobic move used to display pleasure with one's self, to distract others, or to recover from a fall or stumble. Move is composed of the right leg being thrust back while the left leg is bent at the knee (similar to Warrior One Pose in Yoga). The arms are elevated at a 45 degree angle with fingers pointing straight (like how Superman flies.) Upon completion of this move, the mover yells out "Superstar!"
Comes from Molly Shannon skit on Saturday Night Live where she plays the neurotic Catholic schoolgirl Mary Katherine Gallagher.
After tripping on the carpet, Jym recovered with a great Superstar! move.
