Bookdwarf and I have a secret code that served us particularly well throughout our vacation in Spain: whenever we saw someone wearing a particularly ridiculous outfit, we would tap or squeeze hands three times.
This was very useful because there were a lot of ugly tourists, but also because the full-on mullet is very much in fashion in southern Europe right now. Among the young radicals, it has morphed into a mullet consisting of dreadlocks or even a mohawk of dreadlocks. A lock-hawk, if you will. The hipsters, they amuse endlessly.
