When I go with my group, what we say depends on where the cache is located. Our favorite phrase is "Saints preserve us!" said with a very loud and abrasive Irish accent (comes out as, "SAINTS PARSARVUS"). The most memorable use of this phrase was when we finally spotted a cache suspended from a tree branch 30 feet or so from the ground. It was repeated more urgently and at a higher frequency the farther above the ground I climbed. Needless to say, the saints did indeed preserve me, as I did not fall to my death or become impaled on a tree branch . After that, the phrase became a sort of good luck ritual for when we found caches that were dangerous to obtain.
