An acronym that stands for: Never Before Midnight

This means that nothing important ever happens before midnight.

So you can do whatever you want, drink, eat, party, etc. But all the stuff you will really enjoy and remember will happen only after midnight.
Dan and his crew totals subscribe to the theory of NBM. They get together at night, hang out, drink and eat. But rage hard some time after midnight!
