Diogenes the Cynic was called a dog.

Diogenes the Cynic was dubbed a dog.¿

In one video I saw recently, they said something along the lines of "a serial killer who was dubbed..."

Dub is different. In the case of a serial killer, nobody knows his real name, so they have to come up with a name, dub him something, to call him in the press, etc.

Но ведь диоген киник.

Got it! 👍🙏
