When player takes damage, this addon plays "Ай больно в ноге" (ah, it hurts in the leg) sound (meme), unless there is less than 10% of max hp left, then this addon plays epic music that references to a meme where student jumps from the roof and dancing.
This addon is intended to amuse people when they fall in the game and especially in mountainous areas, for example in Zandalar.
