In this video, a bully throws a punch at a student. They go out of frame for a second, and when they come back the bully has wrapped an arm around the student's head as if he were going for a guillotine choke (a.k.a. front headlock). The student throws the bully using the arm wrapped around his neck. I want to learn how to do this throw, but I don't know what it's called. What is its name, and what art is it most likely from?
