What is Buttknuck?
1.
When you're stomach hurts and you rush to the bathroom, everything comes out and it still feels like there's more so your body involuntarily convulses through your stomach to try and push the rest out even though it's all gone.
My stomach hurt so bad that I ran to the bathroom and I had to end up sitting there for 5 minutes after just buttknucking. God I hate that.
