You-Know-Who

The unspoken one

You-Know-Who is a placeholder for a name the speaker won't say aloud—whether from fear, discretion, or dramatic effect.

The phrase gained cultural weight from the Harry Potter series, where characters avoid naming the villain Voldemort: You-Know-Who has returned.

Outside that context, it refers to anyone whose identity is understood but left unspoken: I hear You-Know-Who got fired.
