Is the phrase "Because of what?" a sentence fragment?
To me, it sounds like an incomplete thought and bad grammar.
*****EDIT: Thank you, Patty T!
I actually asked about the *wrong* phrase. I am sorry. :-(
I meant to ask if "Because what?" is a fragment.
"Why did you do that?"
Certainly, it is not a phrase that one would use in formal writing. It is informal and conversational, meaning "for what reason?" Conversational speech is full of incomplete thoughts. The rest is filled in with non-verbal communication and words implied through context. Even a teacher might use this phrase in class, looking for the students to fill in a blank. Without knowing the exact context, I can't say whether it is bad grammar or not.
In answer to the edit of your question, I have to say the same thing. This is informal and conversational. It is a very common expression used to indicate that you want the other person to elaborate on the reason. This is not an expression that I would consider "bad grammar." Yes, it is a fragment. But people speak in fragments constantly. Bad grammar would be something like using the wrong form of be ("I be" instead of "I am") or using slang or other improper words (such as ain't and irregardless) in a situation that should be more formal.
