despero anos a de sti da

The story:

I could never remember the right words and ended up saying nonsense. The above means a despero (no real Spanish word but it sounds like desperate) anuses a de sti da. I used to think it said a merowendo a de sti da. Once I joked, with my wrongly memorizied lyrics, joked it said a mirror window that Peety saw and also A desperate Dally that Pony saw, the second after some characters in a book. I always knew it wasn't right.
