Preheat the oven to 450 degrees F. Pat the shrimp dry with a paper towel and place them on a large rimmed baking sheet. Drizzle the shrimp with oil and sprinkle liberally with salt and pepper. Toss the shrimp to coat and spread them out on the baking sheet in a single layer. Roast in the oven for 5 minutes, or until pink. Do not leave the shrimp in the oven any longer than necessary, or they will turn tough and rubbery.
Meanwhile, in a large bowl mix the ketchup, lime juice, beer, worcestershire, horseradish, and hot sauce. Stir well to combine.
Take the shrimp out of the oven and let them cool.
Pour the simple syrup and Tajin seasoning on two small plates. Dip the rims of ten 4-6 ounce serving cups in the simple syrup, then in the Tajin seasoning to garnish the rims.
Once the shrimp are cool, toss them into the cocktail sauce. Once coated, spoon the shrimp into the serving cups. Chill until ready to serve.
