Whisk together the olive oil, sesame oil, parsley, hot sauce, minced garlic, ketchup, chile sauce, salt, pepper, and lemon juice in a mixing bowl. Set aside about 1/3 of this marinade to use while grilling.
Place the shrimp in a large, resealable plastic bag. Pour in the remaining marinade and seal the bag. Refrigerate for 2 hours.
Preheat an outdoor grill for high heat. Thread shrimp onto skewers, piercing once near the tail and once near the head. Discard marinade.
Lightly oil grill grate. Cook shrimp for 2 minutes per side until opaque, basting frequently with reserved marinade.
