A unit used to quantify ass shaking ability, originally an abbreviation of Nasty Black Stripper. A few reference points follow for better understanding

0 NBS - your standard white guy
4 NBS - your standard drunk chick
7 NBS - Shakira
10 NBS - "this stripper I saw in Egypt once" (the stripper after whom the unit is named)

For clarification NBS is a unit, not a scale, leaving this open ended with the possibility of more than 10 NBS (although this is extremely unlikely)

In addition NBS is sometimes used with 'degree' in a way reminiscent of the martial arts, see the examples that follow
- Dude, check out that stripper, I didn't know that was possible
- Oh man that's gotta be like 9 NBS right there

- ok, highdea, stripperella done right, this chick can shake her ass so fast, that it breaks the speed of sound, and the resulting sonic boom stops villains in their tracks
- oh no way man, that's like 27th degree NBS abilities
