Where Did IDTS Come From?

The IDTS meaning grew out of the same wave of shorthand texting slang that gave us LOL, BRB, and IDK, born from a need to type fast on early mobile keyboards.
While exact origins are hard to pin down, documented usage on platforms like Twitter traces back to around 2017 and 2018, when the abbreviation became a common, casual way to voice doubt online.
IDTS vs. IDK vs. IDC: What’s the Difference?
These three acronyms get mixed up constantly, but each carries a distinct emotional tone.
| Acronym | Full Form | Core Meaning |
|---|---|---|
| IDTS | I don’t think so | Doubt or disagreement |
| IDK | I don’t know | Uncertainty or lack of information |
| IDC | I don’t care | Indifference or apathy |
IDK says “I’m not sure.” IDC says “It doesn’t matter to me.” IDTS says “I doubt that’s true,” making it the most opinionated of the three.
Real-Life Conversations
WhatsApp Chat
“Is the store still open?” “IDTS, it’s already 9pm.”
Instagram DM

TikTok Comments
“This trend is coming back.” “IDTS lol, it never really left.”
Text Message

How Tone and Punctuation Change IDTS
Small details shift how IDTS reads. “IDTS lol” or “IDTS haha” softens the message, keeping it playful and light. “IDTS.” with a period, especially with no other context, can read as flat, final, or even dismissive. Adding a reason after IDTS almost always makes it feel more thoughtful and less abrupt.
Is IDTS Rude?
Not inherently. The IDTS meaning is generally a quick, low-conflict way to disagree. It only risks sounding rude when it’s sent bare, with no explanation, especially in a serious or emotionally charged conversation.
Usage in Different Contexts

Social Media
Used casually in comments and replies to push back on opinions or predictions.
Friends & Relationships
Common in everyday back-and-forth chats, often paired with humor or emojis.
Work or Professional Settings
Rarely appropriate; formal disagreement calls for clearer, fuller phrasing.
Casual vs. Serious Tone
In light conversations, IDTS reads as breezy. In serious discussions, it can come across as too blunt without added context.
Common Misunderstandings
Thinking It Means “I Don’t Know”
IDTS expresses doubt, not uncertainty. That distinction belongs to IDK.
Assuming It’s Always Rude
Most of the time, IDTS is simply efficient, not disrespectful.
Using It in Sensitive Situations
Bare IDTS in an emotional conversation can feel dismissive, even if that wasn’t the intent.

On Snapchat
Used the same way as everywhere else, typically in quick replies to snaps or chats.
On Instagram
Appears frequently in comments and DMs, usually paired with a follow-up reason.
How to Respond When Someone Uses IDTS

Asking for Clarification

Providing More Context
Following up with your own reasoning keeps the conversation moving productively.
Casual Follow-Up
A simple “fair enough” or “okay, why though?” keeps the tone relaxed.
Should You Use IDTS in Professional Settings?
No. In professional or formal writing, it’s better to write out “I don’t think so” in full, since abbreviations like IDTS read as too casual for workplace communication.
