The word means rich
, loaded, fancy, toff
, toffee nosed, upper crust, well off, or well to do. The origin of this word actually derives from an old Romany Gypsy
slang word for pennies, i.e. if you've a lot of pennies
you're well to do, rich, etc. In this light, the word posh can be used as a term of light hearted derision. Please note: a wrong but often repeated even on this website is the urban myth is that the word POSH orginated from Port Out Starboard Home - based on based on the position of the more expensive cabins on a passenger ships from England to India - but this is actually nonesense whch has been commonly repeated.
