For the first twenty seven years of Gunt's life he was a fat, angry, bullied, friendless boy living with his momma in a crack shack while drinking and watching Springer and Wrasslin to fuel his intellect. (While momma paid all the bills, until she got to sick to continue working) Ralph dreamed of being the big, loud, fat, angry bully wearing Tommy Hillfiger one day, but would end up settling for abusing and/or harassing women and children.
For a brief moment, and only online, he thought some "cool kids" accepted him and he interacted with them, again only online, but it was top of the world for a grown man living in a crack shack with his mom. He just needed to keep his head down to make sure people didn't focus too much on him, but ofc, his ego got the best of him. Ralph was feeling his oats enough to go to a IRL event and exposed the gunt. Suddenly the real Ralph came bursting out and the ensuing fallout has made the angry, seething, dumb, white trash fat freak flag fly high ever since. The only people left supporting Gunt are people like himself and he hates his own reflection.
It's just been an amusing peeling of the onion ever since the gunt was exposed. It was the ultimate gift for lolcow watchers but the ultimate curse for Ralph (and the idiots who chose to enter or stay in his orbit).
