  • No.
  • Absolutely no way.

The abbreviation IDTS is mainly used in text messages or within messaging apps such as Whatsapp, but it can also be found in public posts on social media platforms such as Twitter or Facebook.

Origin

“I don’t think so” has long been one of the most used phrases in the English language. No matter who we are, we can all find a use for this phrase occasionally — and often even on a daily basis.

The first-ever SMS message (text message) was sent in 1992, by someone called Neil Papworth, but this new mode of communication truly became popular in the late 1990s.

The earliest mass social media platforms made their appearance in the early 2000s, and MySpace was the first platform to host a million active users a month in 2004.

Both of these relatively novel forms of communication altered the ways in which people talk to one another forever. Whether due to character limits or because of laziness and a tendency to be a prolific writer, brevity and ease of typing gradually became very important to people.

This is how the abbreviation IDTS, meaning “I don’t think so”, entered the popular lexicon.

IDTS was first defined on Urban Dictionary in 2004, with the note that it was designed for “lazy people who abbreviate”. Judging by the steady rate at which new definitions were added, including in 2022, IDTS remains as popular as ever.
