I'm always hearing about this and I dont know what is it

oh, and what is a legal and illegal bump?

umm have you ever heard of google?

Also a legal bump is a bump that is over 24 hours of time, which fits the rules. An illegal bump is a bump that you should never want to do. It is a bump under 24 hours of time, which breaks the rules. These rules are enforce in almost every part of the forum.

Well I mean, the butterfly move! not the insect lol

tnx for the other answer

Anyone! answer me D=

I guess it went too high with your leg, you need to kick more in the sideways, but it was good, keep practicing your skills and the equilibrium.

A butterfly kick is like a spinkick in the air, only difference is that you use both legs and you are kinda flat. its a 360 modified spinkick

oh tnx ! =D
