"Exactly, you know damn well who you are !"
An exclamatory sentence, or exclamation, is a more forceful version of a declarative sentence. In other words, an exclamatory sentence makes a statement (just like a declarative sentence), but it also conveys excitement or emotion. An exclamatory sentence ends with an exclamation mark (!).
