The idiomatic meaning of "big deal" is typically to express that something is not important or significant. It's often used sarcastically or dismissively. While it can occasionally be used literally to describe something truly important, the idiomatic usage is far more common.
The origin of the phrase is relatively straightforward, arising from the contrast between the literal meaning of "big" (large, important) and the intended message of insignificance. It likely gained popularity in the mid-20th century.
The register of "big deal" is generally informal or neutral. While it can be used in some formal contexts, particularly when written, the sarcastic tone might make it inappropriate for very serious or professional settings.
"Big deal" is a flexible expression. It can be modified with adverbs like "really," "so," or "that." It can be negated ("no big deal," "not a big deal"). It can be used in questions ("Why a big deal?").
What sounds unnatural is using it in contexts where genuine importance and gravity are required. Overusing it can also sound repetitive and insincere. A purely literal interpretation of the words in a situation where the idiomatic meaning is expected will likely lead to confusion.

Yes, but rarely. While it can occasionally describe something genuinely important, the expression is almost always used idiomatically to express indifference or sarcasm. Pay attention to the context to determine the intended meaning.
Both "big deal" and "so what" express a lack of concern, but "so what" tends to be more direct and even confrontational. "Big deal" can be more subtle or sarcastic, while "so what" directly challenges the importance of something.
Be mindful of the context and your audience. Remember that "big deal" usually means the opposite of what it literally says. If you want to express genuine importance, choose a different phrase like "significant," "important," or "crucial".
