A long time ago my mom and I heard Mike Tyson tell an interviewer that he just wanted to "Fade into Oblivion" but he misspoke and said "Fade into Bolivian", so we prompted started to use "Bolivian" instead of "Oblivion". And instead of saying "oblivious" we say "bolivinated".

Ex: "Look at that girl, she is so bolivinated."

I also tend to slip Japanese words into things now. Like "Gambatte" for "Good Luck", "Shoganai" for "Oh well, can't do anything about it", and "Deshou!" for "I know, right?"
