Rule of cool
Effects and actions in movies that are 100% impossible but we love them so much. Such as punching through a wall or hang gliding with your t shirt. Also may include but is not limited to, hanging on to cliffs or long periods of time, curving bullets, dodging bullets, antagonists having horrible aim allowing the hero to escape easily.

guy#2: Calm the fuck down dude rule of cool.

Rule of cool
In short, the Rule of Cool states “The limit of the Willing Suspension Of Disbelief for a given element is directly proportional to its degree of coolness. Stated another way, all but the most pedantic of viewers will forgive liberties with reality so long as the result is wicked sweet and/or awesome.
In an RPG, the Rule of Cool means giving your players the chance to perform ridiculous stunts or bend the rules a little bit in the sake of an awesome scene.
