In Sweden it goes

1. eat rotten herring (which you'll not enjoy, because it's rotten fish, yo)

2. clean your palette with a disgusting shot of home made malört spirits (or aquavit, equally disgusting)

3. goto 1 until your drunk

4. get laid

Very, very, very few people ever reaches step 4.

Most commonly it is pickled herring. I don't think rotten herring is a thing in any broader circles.

Homemade bäsk is usually much better than factory made Bäska Droppar, if you enjoy the taste of wormwood more than just being slapped in the face with artificial bitterness and sugar.

Of course, if you hate the taste of fish, pickled things and spirits in general, you are unlikely to enjoy any of it.

Surströmming is not pickled but rather fermented

Aquavit equally disgusting? I guess I should try malört :) Aquavit with beer chaser and https://en.wikipedia.org/wiki/Pinnekj%C3%B8tt is a great Christmas dish (but I would die if I didn't keep it to Christmas)
