seatbelt enema
happens primarily during early childhood, but can occur in rare occasions in adulthood; when you hastily hop into the back seat and land the middle of your ass cheeks on the seatbelt, and you feel a pain like no one can describe that takes over your body and a vocal fray/grunt leaves your mouth that you can’t control.
mom: be careful! don’t jump in too quickly you’ll give yourself a seatbelt enema!
