Definition: Acronym for "that feeling when."

Sample usage: "TFW you know your school project is going to be the best one the teachers have ever seen even though it's eerily similar to the one your older brother turned in two years ago."

Popularity: It's already big. It's an acronym, hence good for text and Twitter. In fact, that's the only place you can use it. Don't go around saying "tuffwuh" and thinking the kids will get it.
