Griff: Noun/ Verb. To make an Irrational decision in the spare of the moment that others just do not understand. It is usually done by an “Aaron” and in no way is it a Common decision it is quite the opposite. Pretty much you do the opposite of what anyone else would do. After you Griff up you say “WOW” and “Sir” and move on to your next Griff Moment.
