I have been on a Walt Disney World ride that has an Alioramus in it. It's not really new..

Like any other muscles in the body, your abdominal muscles can have spasms that occur as a result of muscle strain during heavy use or overuse, fatigue, dehydration, and alcohol or drug use. Abdominal muscle strain is a common injury among athletes and can cause muscle spasms.
Minor spasms may be the result of exercise or overuse of a muscle. Some spasms may be the result of a neurological condition or injury. Serious causes of spasms include kidney disease, seizure, and stroke.
