Does it mean someone is annoyed?

There are two popular methods to employ ISTG in your messaging, with the meaning changing based on the context. It might indicate that you're frustrated or that you're attempting to be truthful. Because they are two separate meanings, they should not be confused. For example, if your friend is upset by the entire chat, you might not want to give a cheerful response.

For starters, the acronym might indicate that you are upset or annoyed by anything. An "annoyed" ISTG is usually given with a sarcastic joke or a suggestion of someone's dissatisfaction, such as "ugh." Someone may tweet, "Ugh, istg if this rain doesn't stop soon," to express their displeasure with the weather. The message may also appear extremely harsh, such as "ISTG...", with ellipses being a typical expression of dissatisfaction.
