n. 1. An instantaneous orgasm resulting from very little to no stimulation given. 2. Any sort of other immediate intense gratification with minimal stimulation. {Pepe, from the e-famous 20yr old virgin in Fort Worth, Texas; gasm as a derivative of orgasmos, Greek for swelling, namely of certain organs due to stimulus}
Example: Upon sight of the attractive girl approaching, Pepe immediately ran back to his vehicle, narrowly escaping a public Pepegasm.
The intense pelasurable feeling u get when you let your pee out after having to go bathroom very badly.

A peegasm is when you finally take a piss after holding it in for an extended period of time i.e. a long trip, waiting for an end of a movie or having to finish something and just can’t get away. The feeling makes your legs weak, you feel good all over and you can’t think of anything but what is happing at that moment.
