Millions of soccer fans are eagerly counting down to the first ever "superclásico" Copa Libertadores final between Boca Juniors and River Plate tomorrow.
It's the most explosive and combustible match in a nation in which fans have been banned from travelling to away matches since 2013 due to football-related violence that has seen 305 supporters killed in the last 50 years, according to the Salvemos al Fútbol charity.
Football magazine FourFourTwo as well as British newspapers The Daily Telegraph and Daily Mirror have recognised it as the fiercest derby rivalry on the planet.
The teams' presidents have tried to calm the waters ahead of the match.
One meme involves Homer Simpson wearing a sign saying: "The end is near," while another offers advice on avoiding a heart attack, with images of people watching the game while connected to artificial respirators or holding a defibrillator at the ready.
But it's not been all jovial verbal jousting ahead of the match.
In the northern rural town of Apostoles, far from Buenos Aires, a man accused his ex-brother-in-law of burning down his house following an argument about the game.
Former River defender and Argentina international Ramiro Funes Mori, currently playing for Villarreal in Spain, warned against building the tie into "a matter of life and death" before admitting that "whoever wins will have the glory."
And it will be unprecedented glory for what will go down in history as the most important superclásico ever.
The first of these was played in 1913, with River winning 2-1, although Boca have the edge in the overall head-to-head by 88-81 with 77 matches drawn.
Boca are aiming to match another Buenos Aires outfit, Independiente, beaten 3-1 on aggregate by River in the quarter-finals, by lifting a joint-record seventh Libertadores trophy.
Boca overcame Brazilians Palmerias 4-2 on aggregate in the semi-finals while River survived a contentious last-four encounter with another Brazilian team, Gremio.
The Argentines progressed on away goals rule after scoring a late winner in Brazil from a penalty Gremio argued loud and hard should never have been awarded.
River have won the Libertadores three times but were the last Argentine outfit to do so in 2015.
