In the 77th minute of Barcelona's La Liga matchup with Rayo Vallecano, the Catalans scored the fifth of their seven goals.
In typical Barca fashion, the goal was a beauty.
Right back Dani Alves made a great linking play with Pedro, releasing the Brazilian into space on the right of the box.
Alves received the ball and crossed it into the box, where it flew over the head of Lionel Messi and right to Thiago.
The Spaniard met the ball with a stiff, downward header that beat the keeper and flew into the side netting.
It really was a goal of grace and beauty.
That's what makes what comes after it all the more disgusting.
In celebration of the goal, Thiago ran to Alves, seemingly to acknowledge him for his great build-up.
With a big smile on his face, Alves said something to Thiago; the two then turned to the crowd, watching each other, and proceeded with a rendition of the "Tchu Tcha Tcha" dance.
The crowd, who were voicing a subdued bit of displeasure at the goal, quickly made their anger at the actions very clear in the way of extremely loud boos and whistles.
Even Carles Puyol seemed less than thrilled with the actions of the two who created the goal: the Barca captain ran into the celebration, grabbing Alves and Thiago and pushing them back toward the centre circle with an incredibly irritated look on his face.
Throughout the rest of the match, the crowd made their thoughts about the celebration perfectly clear, even throwing debris at Dani Alves as he was attempting to take a throw-in.
Now, I do not have a problem with celebrations and certainly do not condone the actions of those fans who were throwing things onto the pitch.
Further, I probably would not have had a problem with this if this was the first goal of the match, at home, or even if it was just one of them doing it.
This was the perfect storm of choreography between teammates (this was clearly set up before the match) in a match that was long out of hand in front of their opponent's home fans.
This incident went beyond celebration: it was rubbing in a loss to your opponents and their fans and showing the other team up in front of their fans.
For a goal that puts you up 5-0 in a match, the phrase "act like you've been there before" should be gospel because, after all, you have.
It wasn't cute or cool, it was embarrassing. Just ask Puyol.
All it did was ruin what was a pretty nice goal.
Then again, what else should we expect from Dani Alves?
