When someone is very angry or upset, they might start to show physical signs like shaking, sweating, or even yelling. Sometimes, people might even seem like they're literally foaming at the mouth, meaning that they have a lot of saliva around their mouth that looks like foam. This expression is used to describe someone who is so angry or upset that they are visibly and physically out of control. It is not a polite or respectful way to describe someone, so it's important to be careful when using this expression.
