The Dirty Coner is the act of shoving one's kitchen utensils one by one into your Rectum whilst playing low quality Jump Up Drum & Bass as loud as you can whilst staring intensely at your dog who is doing the circle dance before taking a shit.
"Did you hear about Ethan? I heard he was caught and gave his nan a heart attack whilst performing the Dirty Coner, his dog had to be put down"
