In a large skillet, heat oil over medium-high heat. Add garlic and stir just until fragrant, being careful not to let it brown or burn, about 30 seconds.
Pat shrimp dry and add to garlic. Stir in crushed red pepper. Cook, tossing constantly, until shrimp are completely pink, about 5 minutes; do not overcook. Remove from heat and stir in parsley and lime juice; season with salt to taste. Serve warm.
