Disrepute is when a person or a group has a really bad reputation. A mean prank played by just a few football players, for example, might bring the entire team into disrepute.
If you damage your reputation or dishonor your family in some way, you've fallen into disrepute. The noun is especially useful for describing the loss of esteem for a group, team, or organization: "The scandal sent the entire sport of kickboxing into disrepute." It stems from repute, the general opinion or reputation of something, which comes directly from the Latin word repute.
