How to Sign "Gum"
To sign "gum", start by forming your dominant hand into a bent "V" shape. Do this by extending your index and middle fingers, then bending them slightly at the knuckles. Place the tips of these two fingers against your cheek, near your jawline. Move the fingers up and down a couple of times against your cheek. This movement mimics the action of your jaw muscle when you are chewing a piece of gum.
