The line comes from Jurassic Park, released in 1993, during the visitor centre tour film presented by Mr DNA, an animated double helix character. He explains how scientists extracted dinosaur blood from mosquitoes trapped in amber, and the cheerful Bingo Dino DNA moment marks the breakthrough in that explanation. The clip later circulated online as a reaction sound for discoveries and explanations that suddenly make sense. Its lasting appeal comes from the contrast between complex genetics and a simple, game show style celebration that anyone recognises instantly.
