An urn is a type of vase or container for holding liquids or powders.
Does this mean that we would see an older gentleman sniffing the aroma from vases and suchlike receptacles in public toilets.??? Perhaps he may even place his nose over the toilet pans and even sniff the water in the cisterns. Would his wife join him savouring the piquancy of the experience.?
Certainly an unusual activity.

nope. complete turn off for me...
