How to Sign "Waffle"
Form your dominant hand into a "W" shape by extending your index, middle, and ring fingers while holding your pinky down with your thumb. Hold your non-dominant hand flat in front of you with the palm facing up, like a plate. Tap the "W" handshape onto your non-dominant palm, then lift it, rotate your wrist about 90 degrees, and tap it again. This motion perfectly mimics the crisscross grid pattern of a waffle.
