Do you have words or phrases that are part of your consciousness - part of you - but you haven't spoken them since you were a child? Surprise plates are that for me. When I was very young my brother and I would make "surprise plates" for each other. If either of us was feeling low or ill, we would put a little of this and a little of that on a plate with a paper towel over it to hide its contents until the other one would whip off the towel and say "SURPRISE!"
My sweet Miss Mae is home from school today, and my first thought was "surprise plate!!"
Another one is "Fishy-toe-bite" but that is another story.
