There is no name specifically for it. Not everything needs a name, it's just a 2 on, switch out. But my friends and I jokingly like to call it a "soft pretzel" because it's close to a pretzel, but not quite there.
Easy way to not sound retarded: just say whats you did and forget stupid names id rather hear someone say what they did than hear them say something stupid, other than kfed since thats turned into a standard.
