I got reported for dancing in my enemy's Nexus

Okay, so I was playing aram and everyone died on the map except me. Super minions were rushing in my enemy's nexus and slowly destroying it. It was a clear victory my team and I wanted to celebrate. I decided to dance next to the Nexus until the minions destroy the nexus only to find that all 5 of the enemies reported me for bad manner and I never even said a single thing in chat the entire time. Like how are those reports justified? I dont get it.
