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 exasperation.

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.
