Throwback Thursday. Used on Instagram when you post an old picture of yourself on Thursday. Old pic should be from a different era of your life, not last week. Bonus points if you theme it to the time of year you are posting e.g old Halloween pic at Halloween.

(T)hrow(b)ack (T)hursday. A social media post that references the past. Basically the same thing that the Timehop app does for you every day. Usually used in the form of a hashtag.

Get the TBTmug. It stands for Truth Be Told. It's another way of saying TBH (to be honest) as TBH has been overused ALOT and we all need a change

Get the TBTmug. Thought Break Time
When you are talking to a friend on the computer and you both run out of things to say. If you say TBT you are excused and dont have to say anything until you think of something interesting to talk about, provided the other person says TBT back.
