<human>: I was at the gym today, and I always drink a TON of water when I work out. I sometimes drink it too fast, and when I do, I cough a little. The water was nice and cold and I was warm, so I poured some water into my mouth and drank some but left the rest in there to... enjoy the cold feeling. Well I must've drank half of the water weird, because I started coughing. I violently coughed water all over this guy who was trying for his one rep max. He freaked out from getting water spit onto his face and chest, and his bar tilts too far to the right, so all of the weights slide off the right side, then the left. 

He puts the bar down, gets in my face and says, "Do you have anything to say for yourself?"

I said, "If you had put clips on..." but he stormed off mad.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I coughed water on a guy doing his one rep max, made him lose balance and all the weights fell off, he was mad
