Throwback Thursday (TB) is a social media trend in which people post old photos and videos of themselves. The idea is that you look at the photo or video and remember what it was like back then and how much has changed since then.

TB stands for “text back” and is a way of letting someone know that you have received their message and intend to respond.
Text back is a way to respond to a post on Instagram. When you see a post you want to comment on, you can tap the words "TB" at the bottom of the post and type your comment. You'll get a notification when your comment has been posted.
When someone texts back to you, it means that they want to interact with your post. They could be sharing their own story or showing their support for yours.
What TB mean in texting?
In texting, TB means 'Text Back'. It's the simplest way to let someone know that you got their text and that you'll get back to them later (or maybe even right away).

TB is used in place of "okay" or "yes," as it's quicker to write TB than it is to type out okay or yes.
For example, when you send a text to someone asking if they want to hang out, they might reply with TB. This would mean that they will text back when they have time.
It's also used when someone asks you to do something with them, like shopping or watching a movie. Usually, the person who asked will say TB so that their friend knows that they're busy at the moment but will get back to them later.

If you're trying to figure out what a "Throwback" means on social media, think about how people use it in real life.
You might say this when something reminds you of something else from long ago—when something seems familiar or makes you think about things from the past.
How do you use it?
If you want to use this tag, make sure your photo is at least two years old and has been posted before. You should also include the date on your post so that people know when it was taken.

When you're posting a TB, it's important to choose something that's meaningful to you—it should be something from your past that helps people see how far you've come or how you started out.
You could also use the TB feature if you want to share an update about what's going on in your life. If there's a big event coming up, or if someone special has passed away (like your grandpa).
