If you’ve received a message containing “TB,” you may be wondering what this abbreviation means. Like many short forms used online, TB can have different meanings depending on the conversation, platform, and context.
In social media and casual online conversations, TB most commonly means “Throwback.” It is often used when someone shares an old photo, memory, video, or past experience.

However, TB can have other meanings in texting and specialized contexts. It may sometimes refer to a phrase such as “text back,” while in medical contexts, TB commonly refers to tuberculosis.
The surrounding words are therefore important when determining exactly what someone means by TB.
