Capoeira uses a kick that is kind of, sort of, similar to that, but I’ve never seen anything quite like that in capoeira. I have seen similar things in other systems as well.Yeah that's not a formal Taekwondo kick. I would say that's more capoera than TKD, if anything.
I guess I wonder, what does it matter? Lots of things can work. Similar things can be found within many different systems. Very very few things are truly unique to one method.
