For instance, the acronym can indicate that you are frustrated or annoyed by something. An “annoyed” ISTG is usually delivered with a sarcastic joke or a hint of someone’s annoyance, such as “ugh.” Someone might tweet, “Ugh, istg if this rain doesn’t stop soon,” to express their displeasure with the weather. The message may also appear particularly snarky, such as “ISTG…” with ellipses being a common sign of frustration.

It can also convey sincerity or vouch for the truth of something. You could use this if you’re attempting to describe something that appears impossible or if others express doubts about your story. You might say if you’re trying to persuade others of a supernatural encounter, “ISTG! I saw a ghost!”

2. Emphatic ISTG

There’s another way to use this slang term, which has grown in popularity in the social media age. It is referred to as an “emphatic” ISTG. People frequently use this on social media platforms such as Twitter and Instagram to express how strongly they feel about something.

This definition is typically overly positive, with people using it to express how much they enjoyed something. You could use this to express your thoughts on an album you recently listened to or a movie you recently saw. For example, if you liked a recent Netflix show, you could say, “ISTG, this new show is amazing.”

You can also use it to highlight opinions that, while not unpopular, may be divisive to some. These are also known as “hot takes” — ideas that spark a lot of discussion and debate. For instance, if you enjoy Hawaiian pizza, you could tweet, “ISTG pineapples belong on pizza.”
