JoJo is most widely known as the nickname for the protagonists of the long‑running Japanese manga and anime series JoJo’s Bizarre Adventure by Hirohiko Araki.

Quick Scoop: What “JoJo” Means

  • “JoJo” is a short nickname formed from the Joestar family name; almost every main character has a first/last name that can be shortened to “JoJo.”
  • The story follows generations of the Joestar bloodline across different time periods, each part starring a different “JoJo” as the lead.
  • The series mixes supernatural battles, flashy poses, fashion‑like character designs, and over‑the‑top drama, which helped “JoJo” become a big pop‑culture meme online.

The Different JoJos

Each part of the series has its own “JoJo” (examples):

  • Jonathan Joestar – the original gentlemanly hero of Part 1. His initials give the first “JoJo.”
  • Joseph Joestar – his grandson and the second “JoJo,” a trickster‑type protagonist who later becomes a mentor figure in later parts.
  • Later parts introduce more JoJos (like Jotaro Kujo and Jolyne Cujoh), all linked to the Joestar bloodline and the “JoJo” nickname.

Why JoJo Is Trending So Often

  • The manga has run since the 1980s and keeps getting new parts, so “JoJo” stays relevant with each new arc and adaptation.
  • Online communities, fan wikis, and forums constantly discuss characters, battles, and memes, keeping “JoJo” a recurring trending topic.
  • The term “JoJo” can also be used loosely in forums to mean “any JoJo protagonist,” which is why you often see people asking “Which JoJo is that JoJo?” in discussions.

TL;DR: When people online say “JoJo,” they almost always mean the main characters from the anime/manga series JoJo’s Bizarre Adventure , where each generation of the Joestar family gets their own “JoJo” as the lead.
