It's summer again and German girls like to show off their "Arschgeweih".
That's a slang expression for the ornamental/tribal tatoos that many girls
carry on their small of their backs. It translates ca. to "ass-antler".
Antler because of the shape of this kind of tatoos.

In my opinion it's ridiculous that every second girl has one but the
question is, has this fashion reached your country and do you have
an extra expression for it?
