Wow. Teen drama.
Unless you are a starter in the game, there is NO FN WAY it is going to affect you in six months, let alone for the rest of your life.
You're wearing a trash can. Great. If you think no one does things like that in college football, you've never been to a college football game. So get involved in rally squad or the band or whatever in college. After the first game, you'll never even think about high school football again.
You might get away with being immature and irresponsible, but that's really the important thing here. The job may suck, but you can get some benefits from your supervisor even if your next job has nothing to do with groceries. "He's a very responsible, dependable worker" is about the best you can get at this age. It's gold. Stupid bridge to burn for a game.
So, ask your supervisor. He may be reasonable. If he isn't, THAT is your responsibility.
And if this is a "pickle," you lead a sheltered life. Kinda stupid to blow a work ethic over it. A real pickle is when you get fired and can't find another job because your previous supervisor says you're a flaky loser, and you have to choose between eating and paying the rent.
Sorry for the wet towel, but you asked for advice. The other stuff in this thread is very bad advice. Get out of your job legitimately, or miss the game. You'll get over it. Fast.
As for never seeing underdogs win again, here's a story from my alma mater (Cal), as reported by the other side:

regular cliffhangers that have been going on for more than 100 years between that rivalry.
