numbers 

A rather brutal and secretive group of prison gangs in South Africa. Number gangs have numbers instead of names, and typically have millitary-style hierarchy, extensive tattoos, strict internal laws, and require violence against prison staff for initiation. The 28 Gang also has a system for distributing sex between new recruits and established members. Recently featured on a BBC documentary.

Numbers gangs include the 26s, 27s, 28s, etc...

Nubber 

Nubber is actually older than any of these previous definitions. It was invented in Belper, Derbyshire, UK sometime in the 1980's, possibly the late 1970's.

It is used to describe a particular person who has done something a bit dodgy, like nicking a fag end from an ashtray or just being generally trampy.

It's not as specific as Pikey, but has similar connotations.

It was also used in shouting competitions, where one person in the group would call somebody a Nubber and they would be answered with, "Did you just call me a NUBBER!" until it ended up whoever could scream it the loudest got mucho Kudos.

"You just picked that up off the pavement. You f*****g Nubber!"

"Have you been wearing the same socks for 8 days? What a Nubber!"

fuck by the numbers 

A mathematical way to have sexual intercourse.

He: Honey, what hole are you looking to have filled?

She: I’m so horny … try ‘em all. Let's fuck by the numbers.

He: OK, I think I will go around the horn. I’ll start with numero uno (mouth), proceed to #2 (pussy), then finish in #3 (ass).

<Fuck cycle can be a continuous loop, or can be mixed up a little … going, for example … 3,2,1 or 3,1,2 or 2,3,1, or 2,1,3 or 1,3,2. The introduction of both nostrils … holes 4 and 5, can be added to spice things up a bit.>
