Mix the hot sauce, Worcestershire, oil, cilantro, sugar and garlic in a glass bowl large enough to hold the shrimp.
Add the shrimp to the bowl and place in the refrigerator.
Allow the shrimp to marinate for 1 - 2 hours. The longer the time, the spicier the shrimp, but don't go past 2 hours.
Preheat the grill to medium-high.
While the grill heats up, skewer the marinated shrimp.
Grill the marinated shrimp skewers for about 3 minutes per side. Be careful not to over-cook the shrimp, they are done once they turn opaque.
