Poshing

Persistent pouting amidst a life of luxury.

The action of releasing your feces by letting it casually slip out instead of pushing it out.

very classy or sophisticated

The word means rich, aristocratic, wealthy, 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.

The space left in your wallet after a particularly drunken and expensive night out. Normally after being invited on an aquaintances birthday/stag night to go somwhere you would not normally go due to the expense. Anywhere on Broad Street for example.
The best way not to get poshed is to get the first round in. Then later in the night, when your compadres are drunk you can seagull a few drinks from them.
How to realise that you are getting poshed: when it dawns on you that the content of your wallet will either stretch to a curry and a taxi home, or one more drink - and you get the drink.
A popular place to get poshed is a distant cousin's wedding where the free bar has been withdrawn. Thus you end up drinking your taxi fare back to the B & B and having to scrounge a lift from some pissed-up arse in a Range Rover.
