Definition: A frenemy is a person who is both a friend and an enemy. It's a combination of the words "friend" and "enemy."
Use case: You use the term frenemy when you have a friend who you also compete with or who you don't completely trust. For example, if you have a friend who always seems to be trying to one-up you or who talks behind your back, they could be considered a frenemy. It's important to be aware of frenemies in your life and to set boundaries with them to protect yourself from any negative or toxic behavior.
