idk 

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."

Last time you dreamed something really crazy and then it happened the next day: Idk lol
