Modern Swedish word for drinking an undisclosed amount of
beer. Commonly used by
math and physics studens, where you, in their litterature, may find that the small letter n is used to define a natural numbers 1, 2, 3....
Öl, or sometimes Öhl is the swedish word for
beer and öla is the activity of drinking said beverage. Nöla, naturally, means drinking an unspecified amount of
beer.
Nöla is also a double pun, where when said straight out, it sounds somewhat like knulla, which means fuck in swedish.
The letter n also has the same sound as the word
En, which means one in swedish. As such, you can fool a spouse,
mother-in-law or concerned parts by saying: "I'm going out to have n öl", basicly any number of beers.
