This happens when the old guy at work sneezes, and blows his chewing tobacco everywhere. Thus, simulating a tornado built from grains of chew and sneeze wind.
Holy chit! Did you see Gary's chewnado? It about knocked over that lamp!
He's a person that likes alot of girls, he always has a hookup every second of the day... hes hard to understand and loves farting and llaying oractical jokes on his closest friends. Likely said he is a jerk in general.
