In JoJo's Bizarre Adventure, "donutting" is the action of punching someone in the stomach so hard, your arm goes through the other side. This makes a hole in the middle of their body, resembling a donut.
Avdol: Kakyoin died because DIO donutted kakyoin.
Joeseph: what the fuck does that mean Jotaro: when you punch someone so hard their arm goes through the other side.
Joeseph: wtf
