sissy pig
A figure of speech that describes how a person or an object is moving, typically in a digging or burrowing motion against something. An example can be a buoy dropping into water and shaking as it starts to float, or when a wood beam holding a roof shakes in mud as it becomes loose and lets the roof collapse. The action of doing something as a "sissy pig" is as if someone shook and rubbed their face back and forth in something, just like a pig that digs its nose into its food.
The man was waxing the floor really fast like a sissy pig, because he was scraping and scratching the floor too hard!
