Mix cream cheese crab meat green onions garlic soy sauce fish sauce Worcestershire sauce salt pepper sesame oil and cayenne pepper together with a fork until ingredients are blended thoroughly. Cover with plastic wrap and refrigerate until chilled 1 or 2 hours.

Keep wonton wrappers moist by covering with a damp paper towel. Place a small bowl of water nearby on the work surface. With a wet fingertip moisten surface of wonton. Place 1 1/2 teaspoons of crab filling in center of wonton. Fold 2 opposite corners toward each other over the filling but without touching tips together yet. Fold up the other 2 corners. Working gently from the bottom squeeze out any air bubbles; pinch together the 4 seams from the bottom up to create a modified pyramid (or \warhead\) shape. Place on a dry surface. Continue with remaining wontons.
