"M-Night" is "
Monday Night", of course.

At least, that is what was always said (on a yearly basis),

in my own church, as M-Night, was always on a Monday.
Seriously, Ed Edwards is correct. This was an annual Associational event of the
BTU, short for Baptist Training Union, among Southern Baptists, in those days, and I attended two or three, when I was a teenager, If I recall, correctly.
I've not heard of it, for several years (and I was the Assistant Church Training Director in my own church for about 7-8 years, so I believe it preceded my own time in that role), so do not know if any such thing has been done, anywhere in the last 20 years or so, but at least, we have not participated, lately, if such even still exists.
