How to Sign "Oatmilk"
To sign "oatmilk," begin by fingerspelling the letters O, A, and T with your dominant hand. Immediately after the 'T', transition into the sign for 'milk' by opening your hand and squeezing it closed into an 'S' shape, repeating this squeezing motion twice. The 'milk' portion of the sign mimics the action of milking a cow.
