Often exported to other EU states with no local instructions of any kind. The actual word 'Achtung' means 'Warning' in German, however it's often mistaken to be a brand name.

The sound of hocking, and then aiming the hock to perfectly hit the rim of the spitoon to make the "-tung!!" sound. It made everyone pay attention, hence its other, more common definition. Alleged to be the first word in the German language, on which all other words are based.
