also used to describe any horrible fecal experience
I hope that aint a mean gene comin' on because we are miles from toilet paper.

Some say the name doesn’t fit him because he is an easy going gentle giant of a man! Loyal to a fault, however if provoked he will unleash hell on you!

You don’t tug on Super Man’s Cape, you don’t spit into the wind, you don’t pull the mask off of the Lone Ranger and you don’t mess around with Mean Gene!
