I am told there is a song sometimes sung at weddings before the bride:
כשם שאני רוקד כנגדך ואיני יכול לנגוע בך, כך לא יוכלו כל אויבי לנגוע בי לרעה
(The original purpose of which is the blessing on the New Moon.)
Isn’t this Nibbul Peh (profane speech), based on the bolded words? Also, there are rumors of ugly talk when escorting the couple to and from the Cheder Yichud.
Is this true?
