Vomiting with enough force while going down on a girl to finish her off.
After a big night on the drinks I was going down on the missus and started to feel the room spin. I knew she was close so I persisted but as she was about to cum I power chucked in her spasm-chasm and the force from my puke finished her off. That night the Down Under Chunder Wonder was born.
