Idiots will use this interchangably with idc. It's supposed to mean "i don't know."
person: idk about you
person 2: do you use idk and idc interchangably
when you don't know something (stands for i don't know)
idk ( it's stand alone)
It stands for "i dont kick" or a short of "i dont kick your ass"
hey jeffrey, can you kick my ass?
sorry, idk
Idk means i don't know. If someone texts (asks in messages) you a question you don't know, you simply text back ''IDK''.
''Do you know what's 20\2?'' idk.
