istg

What does "istg" mean?
"Istg" is an acronym for "I swear to God." It is used to emphasize the truthfulness of a statement, to express frustration, or to show extreme disbelief. The mental image is someone holding their hand up or looking very serious to prove they aren't lying. It is strictly informal and used almost exclusively in texting or social media. While it can be used to add weight to a promise, it is frequently used in hyperbolic ways, such as "I'm so hungry, istg I could eat a horse." It should be avoided in professional or academic writing.
