I have no idea what language that is, but I understand it's about the urban legend of Mr. Gorsky. They say that when Armstrong was a young boy he had a neighbor called Mr Gorsky. He wanted oral sex from his wife, but she replied that she would give that when the kid next door walks on the moon, meaning never. The legend goes that when Armstrong stepped on the moon he remembered his old neighbor and said "Good luck Mr. Gorsky". Anyways, it's only an urban legend and he really didn't say such thing.
