PriceWaterhouseCoopers. Created after a merger of Price Waterhouse and Coopers & Lybrand, PWC is one of the "big four" (final four?) accounting firms. The final four are Ernst & Young, PWC, Deloitte, and KPMG.
From many accounts PWC is "The last form of slavery in the US. This is where many young people begin careers and work 115 hours a week until they either quit or die from exhaustion. Former PWC employees often have scarred backs from the whip marks."
In common with all other Professional Services Firms, PWC really have no place being defined in anything called "the Urban Dictionary". It'll just end in tears before bedtime I tell ya!
Yo ma wigga, PWC be trippin on dis Sarbanes Oxley shizzle. Tru dat.
