A Vomosaurus Rex is normally induced by drinking excessive amounts of alcohol.

Vomosaurus's must make them selves resemble a Tyrannasaurus Rex during the act of vomiting by bearing their teeth, bending their arms and sticking out two didgets on each hand.

They should also growl or make noises resembling a T-Rex during vomiting intervals.

Thus becoming a Vomosaurus Rex.
