BS”D
The story is told of an extreme meshichist, a real nut who I know to be off center, who named his kid Boruch Haba Melech Hamoshiach. The poor kid is known by an acronym made up of his initials – beis hay mem hay – behema!!!!
I don’t know if this is true but I’ve heard it tens of times.
Rav Adin Steinsaltz (Even-Yisroel)’s eldest son’s nickname is A-Mechaye, made up of parts of his first names. This is true; all mazal tovs posted for him refer to that name. I forget what the names are, probably Avraham Moshe Chaim.
