The process of inserting a gerble into a test tube and inserting the test tube into your anus to increase sexual pleasure.
Someone told me this story,
I went down to my apartment building to find it surrounded by police officers, so i went up to one and asked them what was going on, he told me that there were two men upstairs who were gerbling and one got stuck in the man's anus, so they were trying to get him to defecate it out along with the feces.
