IKILYDIBAFTMS Is an acronym for "I know I've let you down, I've been a fool to myself".
It often means the person that is saying this regret something they've done and are emotionally unstable. You might hear it from your mentally ill friend after they treated you bad or ignored you.
-Dad! How could you abandon me, ignore me and abuse me in every single way possible!
-Ikilydibaftms, now get in the robot son.
-Okay dad, I'd do anything to make you proud!
