To be upset is to be disturbed or very unhappy. You can be upset, and you can also upset someone — but you probably didn’t mean to.

Upset has multiple senses. It generally refers to something that has been knocked over, turned upside down, or disturbed. Just as your coffee cup can be upset — knocked over or disturbed –- so can your emotions –- and your stomach. Upset can also refer to an unexpected victory. You might be so upset by the upset of your favorite team that you upset your table in frustration.
