The sound is a mashup of two long-running internet jokes. Sad violin clips have been used online for years to sarcastically score minor misfortune, while air horn blasts became a staple of MLG montages and loud meme edits in the 2010s.

Creators keep using it because the setup is instantly readable even without context, and the horn makes the payoff work as a reaction, a transition or a final punchline.
