Another way of saying that something isn't THAT difficult, keeping in mind that martial arts aren't that easy. Used in a simliar manner as rocket science (when used sarcastically.)
I asked my mom to scan my essay and email it to me, but she found it too complex. I tell her it isn't a martial art, so she hangs up on me and I got an F for that essay.
