Housil, marshmellows are very common in Europe these days.. especially in Germany

because of the many US forces that were located there during the Cold War..
Most larger supermarkets sell them between the candy..
It's about the same as "Speck"
You can get them with the Real, selkro, rewe, nettomarkt etc.. they are called Mäusespeck in German.. (not really the same as Marshmellows, because they often have a little bit of sugar on it, to form a crust when grilling them.. it caramellises)
Sure, someone may one day kill me with my own gun.
But they'll have to beat me to death with it because it's empty.
A computer once beat me at chess, but it was no match for me at kick boxing.
