Party Serious 

Partying serious is much different than partying hard. Partying serious is the much more sophisticated version of partying; it is to keep classy company of the same gender (ladies and gentlemen), whilst in robes, basking in presence of leather bound books, a fireplace, cigars and/or pipes, and of course fine, fine cognac and/or wine.

"We bring the girls in later." Brandon Boyd
