This phrase originated in the southern part of the United States and it derives directly from the word "buck" which has the same meaning as stag. The stag is a majestic animal and so to buck up initially meant to look smarter or tidy up one's appearance. Later, it evolved to being used to mean to cheer up or to just move on after a bad experience.
