The sound comes from Escape from Tarkov, the hardcore extraction shooter developed by Battlestate Games, where Scavs are unpredictable AI scavengers roaming the raid maps. Their shouted barks, including contact callouts, became part of the game's identity because a single voice line can mean loot, danger or an ambush is seconds away. Players clipped the lines from gameplay and shared them across streams, highlight reels and meme edits, where the short alert now works even outside a raid as a universal signal that trouble has been spotted.
