Cross my fingers

What **cross my fingers** means
Thank you in advance

Cross my fingers refers to actually crossing your fingers, usually the middle finger over the index finger.
Crossing your fingers can have several meanings depending on context, most dealing with superstitions or children's games.
You can cross your fingers to bring good luck. I'll keep my fingers crossed so everything will turn out okay
You can cross your fingers when saying something so that it "doesn't count." I said it, but I had my fingers crossed behind my back so it doesn't count."
Some tag-type games you can cross your fingers to be "safe" aka king's X.

Very nice picture and completely accurate. I think that crossing one's fingers so that what you say doesn't count can also be explained as a way of lying, since you don't tell the other person your fingers are crossed. You cross them behind your back, usually. Am I telling you the truth? Cross my heart and hope to die. SS
