And about as effective as telling someone to go "f***k" himelf, and then explaining that you really meant "frisk."

I'll go with my Jewish friends here. It is they who will not spell the name of the Lord. As for biblical justification, try the Ten Commandments.
"This command originally intended to prohibit taking false oaths. More than that, it also forbade disrespect shown to God by using his name wrongly or frivolously. God's name was special. It was the nearest the Israelites came to possessing any part of God, and had to be treated with the utmost care. Later Jewish practice takes this prohibition so seriously that the name of God, and even the word God, was never spoken, with phrases such as "the Lord" and "the Name" used in its place, and G_d used in print."
