Michael Americans find the typical swimwear worn by German tourists hilarious. I was not aware of this fact for a long time and often went swimming in the typical German and tight swimsuits, called "speedos" here in America. I received many strange looks.
What I didn't know was that heterosexual Americans never wear anything skimpier than boxershorts. Anything else may be fashionable on hot days at Dolores Park in San Francisco, where the toned men of the gay scene bask in the sun. But it would never occur to the average American to wear a tight-fitting swimsuit.
Also, even the shorts for men are longer in the US than in Europe. For heterosexual men, it's almost all the way to the knee, if not longer. I would draw the line at a hand's breadth above the knee. In San Francisco's Castro district, around our corner, you can also often see slightly more revealing clothing pieces, like hotpants, but only for those who like it!
In predominantly American-populated tourist destinations such as Hawaii, where few Germans wander, it is a hilarious sight to observe self-confidently striding typically-German (tm) in speedos on the beach who have not yet gotten the memo! Even Linux creator Linus Torvalds, who has been living in America for a long time, seems to be unaware of this fact, as the pictures from the Linus Dunk prove. Granted, it's not easy to figure this out coming from Germany. But once you have, it's quite hilarious!
