It turns out that in Norwegian "Gå løp" literally means "Go run". Not sure if those words in Norwegian are used together in such way very often, but at least I found some examples.
I'm amused that this sounds almost exactly like "Gallop" in English (BTW, there's a word "Галоп" in Russian that sounds almost identical to "Gallop".)
@avp the word gallop comes from French, while Swedish löpa, which I am pretty sure is the same as Norwegian løp is a much older word which is found in various versions in Danish and Icelandic too. It can also be found in English as the word leap.
Now, my French is not very good so I'm not sure how to investigate the etymology of that word.
