Pessi is a long running insult nickname for Lionel Messi, blending his name with penalty to suggest he relies on spot kicks, popularised by rival fans during the Messi and Cristiano Ronaldo debate. The jajajajaja part is Spanish language laughter, the equivalent of hahaha in text and speech online. Together they became a staple chant in short football edits on social media, especially after Argentina or Inter Miami matches where Messi fails to score. The clip keeps circulating because the rivalry joke needs no explanation for football fans.
