On platforms such as TikTok, Snapchat, or Instagram, STG means "swear by God". It is used to add urgency or honesty to statements in posts, captions, or messages. For example, someone can write, "This song changed my life," to show emotional effects. It is often shown in comments, memes, or stories where users want to express their real feelings or reactions. STG helps to make online confidence, severity, or even dramatic weight. Young people and young adults often use it, but it is considered best in random, personal materials, and little in professional or formal places.
