The newest in a long list of annoying internet acronyms, "idk" has become extraordinarily popular with the 13-year-old lie-about-your-age-to-get-on-MySpace grade school slut crowd.

Commonly seen as a BS response when filling out memes and surveys. Double annoyance points when paired with the equally meaningless "lol."
