EUR/NOK quotes the euro in Norwegian kroner, showing how many kroner one euro will buy. It is the primary way to trade the krone, more liquid than USD/NOK, though as a cross it still sees wider spreads and sharper moves than the main majors. It is not referred to by any nickname.
The euro is the base currency and the krone the quote currency, so a quote of 11.6000 means one euro is worth 11.6000 kroner. A rising price means the euro is strengthening against the krone; a falling price means the krone is gaining. You trade EUR/NOK as a forex CFD, taking a position on the price rather than buying kroner outright: go long if you expect the euro to rise, short if you expect it to fall. Despite the larger figure, pips are still counted at the fourth decimal place, and your profit or loss is the pips moved multiplied by your position size.
What moves EUR/NOK most is the price of crude oil, since Norway is a major energy exporter and the krone tends to firm when oil rallies and soften when it slides. The policy split between the European Central Bank and Norges Bank adds to the picture, and because the krone is a smaller, less liquid currency it can move sharply when risk sentiment shifts.
Say EUR/NOK is trading at 11.6000 and you expect the euro to strengthen, so you buy one standard lot (100,000 euros). Each pip is 0.0001 and worth 10 kroner, so a 50-pip rise to 11.6050 gives:
50 √ó 10 kroner = 500 kroner
A 50-pip fall to 11.5950 would instead cost 500 kroner. You trade on leverage, putting up only a fraction of the contract value as margin, which magnifies both gain and loss.
