In a small bowl, whisk together the buffalo sauce, honey, minced garlic, and melted butter until smooth and well combined.
Pat the chicken thighs dry, then season both sides with Slap Ya Mama, pepper, and parsley. Add 2 tablespoons of the honey buffalo mixture and toss until the chicken is evenly coated.
Preheat your grill to medium-low heat. Once hot, place the chicken thighs smooth-side down. For the best texture, cook them low and slow to keep them juicy and tender.
Flip the chicken every 3–4 minutes, continuing until the juices run clear and the internal temperature reaches 165–170°F. During the last few turns, brush the chicken with the remaining honey buffalo sauce for extra flavor.
Finish by topping with freshly chopped green onions and serve with your favorite grilled sides.
