Frenemy
A "frenemy" is a person who pretends to be a friend but actually harbors resentment or rivalry. This relationship often involves a mix of friendship and hostility, where the individuals may support each other outwardly while competing or undermining one another behind the scenes. Frenemies can be found in various settings, including schools, workplaces, and social circles.
The term combines "friend" and "enemy," highlighting the dual nature of the relationship. Frenemies may engage in friendly activities together, but their interactions can also be marked by jealousy or passive-aggressive behavior. Understanding this dynamic can help individuals navigate complex social situations more effectively.
