What does ISTG mean?

ISTG is an acronym that stands for ‘I Swear To God.’ The term is primarily used to emphasize a point you’re making and can reiterate anger or annoyance. It’s similar to the term ‘ONG,’ which stands for ‘On God.’

You will often see this used at either the beginning or end of sentences, for example, “ISTG I can’t take him anywhere,” meaning: “I swear to God I can’t take him anywhere.”

Some people say they originally believed ISTG to be referring to Instagram, so there is a chance you could see it in this context, but most often it is used to mean ‘I swear to God.’

ISTG is by no means a term used exclusively on TikTok, so you may see this pop up in text messages from friends, or in posts on a number of other social media platforms, like Twitter or Instagram.
