Atlas Run - at the end of the round (usually a TSA match), when the results are hopelessly clear (hueg points difference and little time remaining, or tickets something like 100-0) but there is still some time left, one or the other side, usually the victor, may decide to roll into the enemy main with the heaviest assets they can get. While this would be considered spawnkilling when the round is still undecided, at the very end people usually accept it or even take it with humour.
