A word used by gifted and talented (and by gifted and talented we mean pretentious) people to simply describe the word aerodynamics. These people often needlessly argue on YouTube in order to prove their superiority, when in fact they are most likely arguing with a 6 year old (who inevitably wins said flame-war). Often socially shunned and overweight, having much the shape of a potato, these individuals are not very aerodynamic. You could say they lack "areodynamism".
Due to Billy's lack of aerodynamism, he could not run to McDonald's fast enough.
