uncle
UNCLE: Hold a "U" hand to the side of your head. Twist your wrist twice. The sign Uncle is done higher up than the sign "Aunt."
Uncle: (variation)
Some people shake a "U" handshape side to side using a very small repeated movement. Again, the position is to the side of your head, a bit higher up. (Near your ear or higher, rather than near your cheek or lower.)
