The overwhelming sense of elation felt after a massive introduction of dopamine and andrenaline of one who just performed a foolish, dangerous and generally life threatening stunt. The stuntgasm can even be increased by endorphin release in case of a slight injury being sustained in the process of said stunt.
After backflipping from the roof of his garage, little Rodolfo felt the stimulation of a stuntgasm.
