The term 'crouch down' can be defined as three different words: hunker (6 letters), SQUAT (5 letters), and STOOP (5 letters). Hunker means to crouch or SQUAT down, usually with the knees bent and the buttocks close to the heels. SQUAT is a similar action, but it involves bending the legs at the knees and hips, lowering the body until the thighs are parallel to the ground. Lastly, STOOP is an action in which the upper body is bent forward and downward from the waist. All three of these words describe the same action of crouching down.
