O-pilepsy
A weird, short-term thing where someone goes into a full-body shake after having the best sex of their life. It's like being hit by a wave of pure joy and then getting thrown into a blender.
He shook like a bag of marbles after that. #Opilepsy
She was shaking so hard, she looked like a earthquake happened inside her.
He was shaking like a man who just saw his boss get fired.
