<human>: Ok so like many other FUs this wasn't today. This was about to years ago when I was a sophomore in high school.

So I went to a movie with all of my friends one night. Like many teenagers who go movies, we were all quite stoned. Now many of my friends are hockey players and, like most hockey players, they all chew tobacco. Personally, I've never really enjoyed it so i was always the only one not dipping. Anyways, the common thing to do when we went to movies was to grab an old soda cup from the trash to use as a spitter. So when we sat down, my drink was on the left armrest and my friend's spitter was on the right armrest. Halfway through the movie, my stoned ass forgets which cup is mine and grabs the cup on the right. I took about 2 and a half gulps of this drink before I begin to think "why is my Coke warm and why is it minty?" And then it hit me like a quarterback getting hit by Ray Lewis: it's my friend's spitter. Mind you that not only did I just drink dip spit but I also drank someone else's old Coke that had been in the trash. I then spit anything left in my mouth all over the seat in front of me (thank God no one was sitting there) and spent the rest of the movie battling horrible stomach cramps and waves of nausea. By some miracle, I didn't puke.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Got stoned, went to the movies, forgot which cup was mine, took a few pulls of someone's dip spit watered down with someone else's old warm Coke.
