When a situation occurs in which one is so overwhelmed by an event that the the use of "drastic" must be combined with the word dramatic to accuratley decribe the situation.
The expression on Mike's face made while he did the poo-poo dance was so dramastic that I shit my pant's
When a dumbass can't differentiate between the words dramatically and drastically and thinks that this is a real word that can be used in everyday life.
Mike wrote on his lab report that after the variable changed the temperature dramastically increased... and thought that it was a real word. What an Idiot.
