It is one of the most used chat short forms. Let’s see how it works, with easy examples.

For example, “Idk where my keys are” means “I don’t know where my keys are.”
People also use IDK to sound softer when they share an opinion. “Idk, I kind of like it” means “I am not fully sure, but I like it a bit.”

Tone: Is IDK Rude?
