Always very neatly shaven

Qu'est-ce qu'un YUP? ou Yuppie? ou yuppies?
Regardez plutôt dans le Urban Dictionary, une mine de définitions en anglais slang (argot) alimentées par les internautes eux-mêmes. Voici ce que j'ai trouvé pour YUP:

Young Urban Person People in their early till late twenties, who have made bucks in business with sheer luck (mostly during the internet hype in the late 90ties). Can be recognized standing in bars boring the shit out of most good looking woman and/or bragging about there just bought second hand porsche or leased Audi A4. They are mostly neatly dressed in suits with their hair glued into shape with too much wax/hairgel and some dandruff residing on their shoulders. Always very neatly shaven and their skin as clean and smooth as their pimples allow it to be.
