I did not use the Brokie-ism, but I saw it in a comic book, which I somehow missed the first time I read the series.
I was reading a back issue of "The Walking Dead" and in this issue, the survivors were running from a large herd of zombies. They came across an abandoned house, and debated hiding in it. One of the group was against it, saying that if one of herd accidentally brushes against the doorknob, and another sees and thinks it is an attempt to break in, they would all mindlessly start trying to break in. He went on to describe them....."there is no rhyme or reason to them in a group that large, they are a force of nature."
