Uh oh, did someone just text you an acronym and you have no idea what they're trying to say? We've all been there, especially for those born before the age of social media who are trying to keep up with the never-ending Gen Z slang.

Paste BN is breaking down common acronyms and slang terms and we won't let you fall behind the times. Here's what "ISTG" means and how you can use it in your next text exchange.

What does 'ISTG' mean?

"ISTG" stands for "I swear to God," an acronym usually used to express the seriousness of a situation or assure you're not joking when sharing a surprising fact.

"I swear to God" isn't just texting slang – it's used in everyday conversations to emphasize the truth at hand. It's not typically used in a religious context, despite the faith-based connotation. The phrase is also used casually with substitutions like "I swear on my life."

When someone uses an "I swear" phrase (acronym or not) they want you to take their word as gospel – pun intended.

How to use 'ISTG'

Here's how to use "ISTG" with friends, family or in TikTok comments:

"She asked him out after practice, ISTG I'm not lying."
"You are so annoying ISTG."
"ISTG if they kill off my favorite character this season..."
"David and Zuhair are so cute together, my heart is going to explode ISTG."
