1. three simple letters that, together, they form a word meaning 'i don't know' in aim lingo. typing 'idk' instead of 'i don't know' is much faster and easier.

2. this word/combination of letters is most commonly found in the same phrase as, "idk, my bff jill?" this phrase is found in those texting commercials.
