What some might refer to as a "metro-sexual". A lifestyle that goes against everything it is to be a man. Common symptoms may include: blaring dance music, bathing in cologne, very well kept hair with a lot of "product", the PERCEIVED ability to be able to pick up any woman they see. You can commonly find them in herds standing in long lines outside "popular" dance clubs, or slipping the doorman a $20 so they can show their superiority to the other chaches in line.
