For s.t. to be gone, finished, no more left.
All of our plates are gone because the one carrying them fell.
The person driving the sled is stupid; all the cassava is finished off (the plants are broken).

Said of fruit like mangoes or coffee, or any that get ripe at about the same time. Cassava also.
Take all of those mangoes in harvesting; get the ripe ones and the unripe ones.
