The eruption was already brewing before we even entered the stadium. It
was, what the locals call "a classic game" where the two teams were
both from Rio de Janeiro and have existing bad blood–and then there's
us, the gringos (what Brazilians call foreigners) caught in the middle,
not too sure which side to pick.
Once inside the stadium you can actually feel the excitement tingling
in everyone's eyes. Some were chanting while others were expressing
their emotion through dance. The sea of red and black of the Flamengo
side greatly outnumbered the maroon and green of the Fluminense. And
they knew it.
After each goal (two from each team) the stadium would tremble. Roughly
90,000 feet of die-hard football fans jump in unison. Torches emitting
red flares and flags are waved frantically and off they go in
Portuguese singing praise.
