Emotional and Psychological Meaning of ISTG

It may express:

Origin and Background of ISTG
The phrase “I swear to God” has been part of everyday English conversation for generations. Traditionally, people used it to emphasize honesty or make a serious promise.

Just as:
- LOL = Laugh Out Loud
- BRB = Be Right Back
- OMG = Oh My God
people also began using ISTG instead of typing the full phrase.
Today, ISTG has become a common piece of internet slang, especially among younger users who communicate through smartphones and social media.
