Dear Richard,
Consider the orginal meaning of 'con'.
Words like 'Nikon', 'con' and 'twat' have different weights in different circles and at different times.
As for culture, wenn ich Kultur hoere, entsichere ich meinen Browning (I release the safety catch on my pistol). The quote is of course Hanns Johst, not Goering.
Mit freundlich Grueßen,
R.
