Background & History
“Sup” has been around since the early days of chatrooms and instant messaging. In the late 90s and early 2000s, people typed faster and shorter to keep up with quick online chats. Phrases like “wassup,” “s’up,” and eventually “sup” took over.
Over time:
- It became part of texting culture.
- Gamers started using it in lobbies.
- Social media users turned it into a casual hello.
- Today, it’s still one of the quickest greetings online.
“Sup” didn’t change much, but the situations where people use it have. Now it can even show interest on dating apps.
