Add mayonnaise, Dijon mustard, regular mustard, paprika, onion powder, cayenne pepper, and dried parsley.
Mix everything together and cook for a few minutes until it's all mixed well.
Put in garlic powder, spicy garlic B-dubs sauce, brown sugar, garlic cloves, and black pepper.
Let it simmer for 5 minutes, sometimes stirring.
Take it off the heat and add pickle juice.
Wait a bit for the sauce to cool before serving.
