A phrase commonly used in strategy games ESP in Civilisation, Europa Universallis where the player creates a massive army of units (typically infantry) and places them all on one tile/ one army and moves them all at once. Used to overpower enemies with quantity rather than quality, often in the doom stacks favour.
