Basically, the biggest ultras humiliation in history that I've heard of, at the beginning of the match the choreography "ONLY DINAMO BUCHAREST" in the rivals colors, imagine rma playing a semifinal in the UCL and instead of the whole stadium displaying a message in white they start showing the Senyera and reading " BARCA Mes Que un Club" or "Visca Catalunya" in azulgrana and red and yellow.
They had no idea what they were displaying, the rest of the stadium was stunned.
