Wario was introduced by Nintendo as Mario's greedy rival and went on to headline the Wario Land and WarioWare series, where his gruff voice samples and laugh became a core part of the character. Short clips of that voice spread through gaming videos, streams and soundboards because they are recognisable even without any image on screen. The Wario 4 clip is shared in that same tradition, used less as a game reference and more as a shorthand for greed, bragging and cartoon villain energy.
