The act of doing a ninja ball
behind someone with both hands and then wrapping them around someones face forcing them to breath in the gasses, thus causing them to first vomit from the smell, black out, and then fall on the ground and convulse.
Man I ate a huge bowl of chili, and I have been farting all day, so I snuck up on RC and did a ninja strangle hold. She vomited, passed out and convulsed. It was epic! Then I continued to Nazi stomp her.
