Don Juan means playboy, like a Casanova. Someone who is good looking and charismatic and seduces many people.
Omg That is so cool omfg. I’M SO SHOOK RN OMG
Wait really? There's a well known story in my country where the main character is called "Don Juan" and he has so many girlfriends, now I know why.
The more you know
If you're from Spain, then that story is the origin of the expression. It's like calling someone "Adonis", it's because of the greek myth of Adonis
Actually I am not from Spain but my country was colonised by Spaniards for 3 centuries. The story I was talking about was "Ang Ibong Adarna" l, a 16th-century Filipino epic poem. It is about an eponymous magical bird and the main character named Don Juan.
What does “Don Juan” mean. Like as in “mi tío Juan”. Like in Spanish. I’m confusion.
