adrenagasm
A word derived from the fusion of adrenaline (a substance produced by the body during intense situations) and orgasm (a sudden explosion of sensation brought on by sexual activity). In this context, an adrenagasm is a sudden burst of neurological activity within the body due to an inspirational event, causing adrenaline levels to increase and the subject to feel as if they are going to wet themselves. Also, hairs may stand on end and the skin may tighten, creating a "staticy" feeling across the skin. These sensations may be brought on by playing fast-paced video games or watching action films or listening to speed metal.
Man, I was listening to Linkin Park and I nearly adrenagasm'd in my pants man.
