Rule One 

Literal translation is 'don't be a pussy'. Most often used when berating someone with 'you forgot rule one' implying that if one has forgotten rule one then they're indeed a pussy.

Dan: I'm a little tired, my boots are chaffing and the wind is blowing in the wrong direction.
Gora: You're in violation of rule one. Get over that kicker.

Rule 43 

In the UK prison population, Prison Rule 43 says that an inmate can request to be segregated from the main population, "for their own protection", or when deemed necessary by the prison authorities, to maintain "good order and discipline."

Segregation is not necessarily isolation as there is - in most prisons an entire wing occupied by those prisoners "on the Rule" or "doing the numbers. " A wing full of segrated inmates can often amount to hundreds, so isolation wouldn't be an issue.

People going on the Rule would probably be convicted police officers, prison officers, judges, sex offenders, clergy and anyone of celebrity status or in public office to name but a few.

The life of a prisoner on a segregation wing or unit, is supposedly better/easier as there's much less violence, aggression and confrontation, due to the permanent threat of being instantly transferred back into the general population.

Prison Rule 43 is more commonly requested by the inmates rather than enforced by the prison authorities.

I want to go on the Rule 43
(I want to be segregated)
NOTE The (43) above wouldn't be spoken. I had to add it to comply with the reference to the word being described
