ND: Why? Its not as if he even said Hashem (which is also meaningless from a Halachic standpoint, and why we use it). Had he said “Amonai” is ridiculous, would you have said the same? How about “Konam”? (which after all means Halachicly Korban L’Hashem)? How about Conan? (as a Konam for Konam).
Where should it end? The Sem girl calling her date “KeliKaKu”? 🙂
