An automated nervous system response; resulting in the display of an injury from a phantom strike.
In the animal kingdom; this is the equivalent of "playing dead" - right before discovery, that in fact - you are alive and unscathed.
UFC 113 when Paul Daley threw an illegal knee that clearly missed only for Josh Koscheck to act like the strike landed, this would be an example where he "Koschecked Out".
<Verb> Vocalizing loudly about your brute intentions in regards to a situation, but physically unaffectual and impotent to actually follow through on that which is vocalized.
<Noun> One who uses brute and outrageous vocalization of their strength and prowess to hide that fact that physically, they have none.
When I saw that my brother left trash on the counter of my recently clean kitchen I koschicked him up and down, but we all know I couldn't kick his ass.
Don't be such a such koschick! Aknowledge your shortcomings and stop mouthing off like you can do something specatular.
