A minor is one of the most common keys for dark, emotional music, which is why a bass tone in that key slots easily under so many different clips online. Short bass sounds like this spread through meme editing because they do the work of a full soundtrack in a few seconds, signalling tension, weight or a joke reveal without any words. Creators reuse it across gaming, reaction and trailer style edits, and its simple low rumble stays recognisable even when the video on top changes completely.
