How to Sign "Diarrhea"
To sign *diarrhea*, start by making a fist with your non-dominant hand and holding it steadily in front of your chest. Form an 'A' handshape with your dominant hand and point the thumb downward. Place your dominant hand just below your non-dominant fist, then move it downward quickly and repeatedly. You can also puff your cheeks slightly to emphasize the action.
