How to Sign "Caca"
To sign 'caca' (or poop), start by making a loose fist with your non-dominant hand and holding it in front of you with the palm facing down. Form an 'A' handshape with your dominant hand (a fist with the thumb sticking up). Insert your dominant thumb up into the bottom of your non-dominant fist. To complete the sign, pull your dominant hand straight down, sliding the thumb out of the bottom of the non-dominant hand.
