'Stale' & 'Stale Share'
Mining pools give each miner some "job" to be done - a bitcoin block header that the miner will hash in search of a share. When a new block is found, or new transactions are added to existing block by the pool, the old block header becomes stale. If someone finds a share calculated from the stale block header, it's considered a stale share and is wasted work.
