In text, "GTS" most commonly means "Going to Sleep" or "Go to Sleep." It is a slang acronym used to indicate that the person is about to go to bed or is ending a conversation, usually at night, to signal they won't respond further until morning. It can be used to politely excuse oneself from texting or social media chats due to tiredness or bedtime.
Other less common meanings of GTS in text include "Good Times," "Google That Sh*t" (used when telling someone to look up information), or context-specific meanings like "Ground Transportation Services" or "General Thoracic Surgery," but these are rare compared to the primary usage relating to sleep.
Hence, the primary and most widely understood meaning of GTS in texting is "Going to Sleep."
