'epicsauce' is used to describe anything that's really cool, or epic for that matter. Technically, you could just use an adjective and 'sauce'. works just as well. Like coolsauce, or failsauce.

In much the same way that "awesomesauce" modifies "awesome," epicsauce is the proper modifier to use when "awesomesauce" just isn't enough. It is epic to the power of ten.
