(Translation: I swear to God, I’ll lose it if it happens again!)

You: “Nope, ISTG.”
So depending on context, it can sound serious, annoyed, or even funny.
⚡ Quick Fact:
“ISTG” was first recorded in online slang dictionaries around 2009, but it exploded on TikTok and Twitter after 2020 — now appearing in over 1.4 million posts monthly (Sprout Social 2024).
Background & History
Before texting slang became mainstream, people would type out “I swear to God” in full — often to show truthfulness or intensity.
But as texting evolved, people began abbreviating longer phrases for speed. “ISTG” emerged in early Reddit threads and Twitter replies in the late 2000s, later spreading through meme culture and TikTok trends.
By 2018, ISTG had become part of the core Gen Z slang vocabulary, used not only to emphasize truth but also to add drama or humor to posts.
💬 Example from a 2021 TikTok trend:
“ISTG this filter makes me look like a potato 🥔😂.”
So today, “ISTG” isn’t just about swearing to God — it’s about expressing emotion in the fastest, most relatable way possible.
