I often see a subject and a verb is omitted in verbal English, is it common?

Yes, that's correct. In casual conversation, it's okay to omit words in this way. The most commonly omitted words are articles (an, the), subjects, and verbs connected to these subjects. You can think of "but why use the word "fired"?" to mean, "but why do people use the word "fired"?" Ex: Why cry for me? I'm not sad at all. (Why are you crying for me?) Ex: Sit down over there. (You can sit down over there.)
