POSH is an acronym for Piece Of Shit

Now why isn't it just POS?
Simply because Posh is also a word meaning 'Rich or trendy' and it's funny how the word and the acronym contradict =P

It come from the day of steamers traveling to the far east from Britain passing by Cape town. The leg Cape Town to the far east was in hot weathers and the ship had the starboard side always facing south. The cabins would get very hot on that side so a port cabin on the outbound jurney was preferable. The reverse applied to the homebound jurney. Hence the most expensive tickets where those: Port Outbound Starboard Homebound, simply marked as P.O.S.H.
Today is is sinonimous of expensive, high class, etc, although should mean Chavvy after POSH spice adopted it.

First Class
As in travel from and to India and England
Because of the position of the day sun the best cabins were always "Port (side) Out, Starbord (side) Home"
