Place it at the peak of a tactical round edit, after an Enemy Spotted cue builds the callout and before a Bomb Has Been Planted line closes the sequence, letting each gaming sound serve a separate beat in the play.
About this sound
A very loud voice shouts the warning phrase 'Fire in the hole' in a clip lasting just under two seconds. The volume and urgency make it hit as an abrupt, funny shock rather than a serious alert, turning a simple warning into an exaggerated jump-scare moment for listeners who expect something much quieter.
