It comes direct from my Aussie friend. DILLIGAF.
"Do I look Like I Give a F---?"
What is it in reference to you ask? Anything and everything that bores you. All the gibberish and palaver and lies and assertions and accusations and flat out LIES. All the posturing and threatening and bullsh** others take as GOD'S TRUTH when we know it isn't. I DILLIGAF the lot of them.
Just DILLIGAF and you'll be fine. DILLIGAF. My newest favorite acronym.
