Beach is a nicer way of expressing your anger. It can be said in place of any "bad" word that you can think of. Whenever your thinking a "bad" thought, it is always nice to resort to beach. Mostly because there might be children around. Also, it doesn't give you the risk of saying something you would regret. A little too often, we take out our anger on beloved family members. By using beach, you are staying away from those "bad" words and taking out your anger in a good way.
