Spike's curse

As usual, It was a bright and sunny day in the Crystal Empire. Birds chirped under the midday sun and Crystal pony's  everywhere sang happy tune's. Today was Spike's day off from working for Twilight, And what better way to spend his day off then a day at the Crystal Empire?

Spike laughed as he ran through the hallways and corridors of the Crystal Castle. He was running from a new "friend" he had met in a dark alley way. He had thought the two were playing a game of chase, But the truth was that  the old earth-pony chasing spike was actually a dragon molester, Though Spike was to stupid to see that.

"You cant catch me," Spike teased as he ran through the castle away from the old pony.

Little did Spike know, but the teasing was actually just turning the old pony on even more.

"Oh, I betcha I can!" yelled the old pony with a sick smile.

The chasing had went on for hours, and by the time Spike had figured out what was going on, Spike was forced into a brutal fight to the death with the molester who knew kung fu. The fight lasted over an hour. But that's another story.

Anyways, Spike was sitting at a curb in front of the "Crystal Castle" trying to catch  his breath while covered in blood, ash, tar and grape jelly, From the fight he had just had. As Spike sat at the curb thinking about the epic battle , something bothered him. Something that scared him.

The chase brought him all over the crystal  empire, and the fight was at a "Toys R us" parking lot.  Right as Spike was about to do the most epic finishing move of all time Using: Barbed wire, a cement mixer, Industry standard explosives, an M-16 and his own two fists, The near defeated pony yelled a chant to Spike. The chant was in a different language Spike didn't understand....But he thought that he had heard the chant before. He just couldn't quite put his finger on it. Anyway's Spike went on to do his finishing move, (As stated before it was the most epic finishing blow of all time) And he walked away from the scene like a boss. A massive explosion behind him as he walked in slow motion.

Now Spike was sitting on the curb. He knew he had heard the chant being used before. Some sort of curse. But nothing came to mind.

The sky was starting to get dark and Spike got aboard a train for home. As he sat in the train, the final words of the old pony kept hitting him up like when Pinkie Pie would kick his nuts. Where has he heard the  chant before?
