Quick Answer: Deku means “a nickname for the character Izuku Midoriya from the anime ‘My Hero Academia’.”
In a broader sense, it can also mean “useless person” in Japanese slang. It’s a friendly, playful way to refer to someone, either as a reference to the hero or jokingly calling them clumsy or inexperienced.

In casual texting or social media, Deku is most often used to reference the beloved anime protagonist Izuku Midoriya, known for his kindness, determination, and hero journey in My Hero Academia.
However, the original Japanese meaning of “Deku” (木偶) can also translate to “puppet” or “useless person”, used as a teasing nickname in certain contexts. Fans of the anime embraced the term affectionately for the character despite its negative origin.
