I once worked with a guy who would greet minor setbacks by yelling out “CACHE MISS!” and anyway that one stuck with me.

“The alternative situation, when the cache is checked and found not to contain any entry with the desired tag, is known as a cache miss. This requires a more expensive access of data from the backing store. Once the requested data is retrieved, it is typically copied into the cache, ready for the next access.”
