<human>: So at my school every year just before we get let out for the holiday brake we have a meeting. It has challenges that are different things.  One of them was for chugging 5 Dixie cups of eggnog. I decided why not and went up. It was about 5 or 6 other people up there. Its a small school and everyone knows who everyone is. So we start chugging the eggnog. I get about 1 and a half cups down before I decided to stop actual swallowing the eggnog. I took another cup before realizing that I had not drunk the preserve cup of eggnog and I opened my mouth. At that moment for whatever reason my body decided "TIME TO GAG" I opened my mouth and the eggnog pored out of my mouth and spewed everywhere. It didn't hit anyone but someone had recored it. It fucking looked like Mt saint Helens had just erupted as I was looking up when I gagged.

Can you provide a brief rundown of the text in within 3 sentences?
