To me, at least, I don't really think of it as "taking balance."
The Japanese term "kuzushi" is often used in situations like this, but I don't really think of it as "balance." Rather, I usually translate "kuzushi" to be something like, "to undermine a structure so as to destoy its capacity to remain standing on its own."
It doesn't take much for kuzushi to be applied. I remember walking up the stairs here at work a while back and nearly falling flat on my face since I wasn't paying much attention and was expecting another step when there wasn't one! If a non-existent stair step can cause that, then it really doesn't take much...
