This phrase is useful because it can describe any very surprising thing or event or experience which you have encountered. Admittedly, many people lead quite conventional lives, without encountering really interesting things, but you never know. This phrase is often useful for when describing event when traveling to other countries. Because it involves so much personal reaction, this phrase is more for spoken, not written English.
