"a minute before midnight," means a person is so dark they almost look like the blackness of midnight.
I only date 11:59's so when we're doing it in the dark the only think I can see is their teeth.

A time used to avoid disambiguation of today/tomorrow when dealing with midnight.
Me: I need you to finish this before Friday 11:59 p.m.
You: Ok sure.
Me: I need you to finish this before Friday Midnight
You: er, so hand it in on thursday or friday?
Me: ... Friday...
You: But Isn't midnight the first moment of the day?
Me: Shuddup.

At 11:59pm in October 31st you start jerking off and try to finish before midnight.

If unsuccessful then you already failed No Nut November so you can just jerk off the entire month but if successful you can say you were the last person to jerk off and you got to have a moment of pleasure before 1 month without it
