Bowser Jr first appeared in Super Mario Sunshine in 2002 as Bowser's son and a recurring antagonist in the Mario series. His laugh became a staple sound effect across later games including New Super Mario Bros and Mario Kart, where it signals tricks, attacks and taunts. Clips of the laugh spread through gaming videos and soundboards because the performance is short, expressive and tied to a well known character. It remains popular for meme edits where a childlike villain energy is needed without using a longer dialogue line.
