That feeling you get right as you're about to fall asleep, where you feel as if you are falling, so you jerk yourself awake while making a yelping sound combined with the sensation of spontaneous orgasm.
Right as Megan was about to fall asleep, she suddenly jerked awake and experienced a yelpgasm due to the sudden excitement.

Get the Yelpgasm mug.The act of putting your face in between a girl's legs with your mouth situated at the opening of the vagina (clothed or naked) and violently yelling at the top of your lungs in to it.
