Where Did ISTG Come From?
Nobody sat down and invented ISTG one day. It just grew out of how people talk online.Back in the early 2000s, people started shortening everything in text messages. You had OMG, LOL, BRB, and then ISTG followed the same path. The phrase “I swear to God” already existed in everyday speech. People just moved it to texting and cut it short.By the time social media got big, ISTG was already common. Younger people picked it up fast. Now it’s everywhere.
How People Actually Use ISTG in Texts
ISTG shows up in a few different ways. Here are the main ones.
1. To sound serious
Someone wants you to believe them. So they write ISTG to add weight to what they’re saying.
Example: “ISTG I locked the door before I left.”
They’re not messing around. They really mean it.
2. To express frustration
Sometimes people are just fed up. ISTG becomes a way to vent without fully exploding.
Example: “ISTG if he texts me one more time I’m blocking him.”
You feel the frustration right away.
3. To react to something wild
Someone shares news that’s just too crazy. ISTG becomes the reaction.
Example: “ISTG I just saw a raccoon walk into Subway like he owned the place.”
It adds drama. It makes the story feel bigger.
4. To back up a claim
You said something and nobody believes you. ISTG works like a verbal guarantee.
Example: “ISTG this is the best pizza I’ve ever had.”
