Derived from the film 'Ong Bok' - A galloper is one who behaves in a certain unbridled manner in respect to any situation. It's obviously a reference to the stiff gait of a wild stallion clopping across the land. One who is acting outside of the realm of proper demeanor is a galloper.
Did you see what that galloper Jermaine did last night?
