Place wings in a large bowl. Sprinkle with salt and pepper and toss to mix.
Heat oil in a deep fryer or Dutch oven to 400 F.
Fry the wings (working in batches as needed) 8-12 minutes or until golden brown and crispy, turning occasionally. Transfer to a paper towel-lined plate to drain.
Meanwhile, melt the butter in a medium saucepan over medium heat.
Stir in the hot sauce and vinegar. Remove from heat.
Once the wings are all cooked, transfer to a large bowl. Drizzle with the toss and toss to coat.
