I still remember the first time I saw someone comment “I’m a sub 😅” on a TikTok post. I paused, stared, and wondered… sub? Like a sandwich?
A YouTube sub? Substitute teacher? None of it made sense. And if you’re here, you’ve probably seen “sub” pop up in conversations or captions and felt the same confusion.
The truth is slang evolves FAST online, and “sub” has more than one meaning depending on where it appears. But don’t worry once you understand the context, it’s super easy to recognize what people really mean.
Quick Answer: “Sub” means “submissive” in online slang, especially in flirty or personality-related conversations. It can also mean “subscribe” or “substitute,” depending on the platform. It’s usually a casual and context-dependent term.
What Does Sub Mean in Text?
In texting and social media slang, “sub” most commonly means “submissive.” It’s used when someone describes their personality, dating style, or preferences — often in a light, flirty, or playful way.
However, outside personal chats, “sub” can also mean “subscriber” (like “YouTube subs”) or “substitute.”
Example
“he’s definitely a sub lol”
Here, “sub” = submissive personality.
In short: Sub = Submissive (most common slang meaning) = A person who prefers a more passive or yielding role.
