A strange position where a character in a generally good mood runs with their arms fully outstretched to the sides like the wings of an airplane. (Try it, it's fun!) Ninja are also frequently portrayed running this way (with the arms swept farther back, like the wings on an F-14 Tomcat), though they now tend to prefer the Ninja Run. Samurai also run in a similar manner, usually while keeping one hand grasped onto their katana. In a more (apparently) realistic series this may have something to do with the runner having a reduced profile and thus being harder to hit with ranged weaponry, but it's generally just the Rule of Cool.
