When you transform from a normal happy person, to someone who throws a random psychotic tantrum.

Tantrumatic 

When someone goes ballistic.

"When the guy from the St. Louis Cardinals from the MLB asked the umpire for some extra time, and then the umpire said, 'No,' then the guy from the St. Louis Cardinals went ballistic and threw his bat...yeah, he was 'tantrumatic'."

When a ballistically angry person goes berserk, and becomes traumatise, by going into shock, without expression, as if frozen.

The football player flew into a tantrum, launched a flying kick, hitting the fan that insulted him, with several blows; and suddenly, becoming aware of what he has done, he looked blank, shocked and dazed, wondering, he became tantrumatise.
