Place the 4 pounds of chicken party wings in a large bowl. Sprinkle with 3 ½ teaspoons salt and 1 ½ teaspoons ground black pepper, then toss to coat evenly.
In a medium bowl, whisk together 1 cup buffalo sauce, ¾ cup honey, ¼ cup lightly packed brown sugar, and 1 tablespoon Worcestershire sauce until smooth.
Reserve 1 cup of the sauce in a separate container for basting, then pour the remaining sauce over the wings and toss until they are fully coated.
Cover the bowl and let the wings marinate at room temperature for 30 minutes.
Meanwhile, preheat your grill to medium-high heat.
Arrange the marinated wings on the grill and cook for about 20 minutes, turning occasionally. Each time you turn them, baste with the reserved cup of sauce.
Grill until the wings are crispy and reach an internal temperature of 165°F (74°C).
Remove the wings from the grill, baste once more with the reserved sauce, and serve.
