Line Rotations or The Offspring Rotation
Basically, you take a line and rotate it, but for the effect in the show, you don't turn the whole 90 degrees angle, you turn it around (only estimating) 20 degrees to give it the pop! And you could also turn it the other way to revert back to your previous formation, before you went into the roation.
(The Color Guard & Drum Line were only in it for effect)
