Pinky Nail

A long pinky nail currently can stand for two extremely different things. One has to do with helping in the consummation of a certain powdery substance.

The other has to do with people showing that they're of a higher class as they don't do manual labor.

This is somewhat similar to how the swastika can have a very different meaning if you just flipped it over.

(But most people prefer to be offended by both versions)
