When a friend breaks off a friendship with another friend, much like a regular breakup. Usually, the dumpee is unaware of why they are being friend dumped.
Amy: "I don't think we should be friends anymore."
Beth: "Why?"
Amy: "It's just not working out."
Amy goes to her friend Suzy.

Suzy: "Girl, you just got friend dumped."
