Metal Gear Solid 2: Sons of Liberty, released in 2001, follows Solid Snake and Raiden through a stealth story that became one of the most quoted games of its era. Short voice lines from Snake have long circulated as reaction clips because his dry delivery is easy to recognise even without context. On soundboards and in gaming videos, this yeaaah is used less as a quote from a specific scene and more as a compact celebration sound, a shorthand for confidence after a play goes right.
