Poshbaws
Someone who is well-to-do or appears to be so. They generally will speak proper and look like they use expensive moisturiser. Often, it is accompanied with the wearing of strange or shit clothes that they tell everyone is designer and so therefore OK. Talk of how many places they have been to in the world and which one of their parents paid, are a must.
"Poshbaws" - loads of people I know that I'm not allowed to mention here else it gets rejected.
