well yeah.. its a wackflip without the grab.. it would be a flat 3 if you added a japan because tweaking the japan would make the flip look more horizontal. In the video below you will see that the kid does a japan with his flat 3, and if you imagine him doing it without the grap, his bodies rotation is the exact same as this kids flat 3 (although it is busted) but in reality i could give a shit and half the time newschoolers is a succubus that creates arguments between kids who wont change their opinions for anything so call it what you want
