My worst experience was the Georgia game in 1980, the opening game of the year, the game where the Vols helped annoint the introduction of Herschel Walker to the world. The game where the Vols let 15-0 at half and lost 16-15.
While that qualifies an absolute awful experience, it was compounded by having to sit next to an oversized dawg. I am about 5'8" and he 6'3" or taller, husky, and apparently strong. Back then, Tennessee sold coke in hard plastic cups that would hold almost a quart of liquid. Understandably, he was quiet in the first half but became very animated in the second half. He was drinking Kentucky bourbon mixed with coke in cup. Every now and then, he would refill the cup with more bourbon. By midway through the fourth quarter he was really hyped up. On one particular play where Georgia either made big yards or scored, he jumped up holding his cup and the contents of the cup kept on going up and pretty much landed squarely on top of my head as he was saying "Go, you hairy dawgs." Nowadays, he would no doubt be thrown out of the stadium. Cannot go around saying "Go, you hair dawgs" at Neyland. I was drenched with the sticky mixture sitting in Section DD which was full of mostly young people who looked at him with disgust but didn't say anything. It was a long evening.
