Happy St. Patties Day!

A greatly random act or action that is sudden and perplexes those who encountered it leaving them dumbfound. A step above random, thus the g for greatly random shortened to grandom.
John: Did you see the guy at the reception with a top hat?
Mark: No why?
John: He was so grandom, he started speaking German and throwing rubber ducks out of his suit case while playing the Macarena on a boombox all while he Capoeira.
