What is Creamfields?

Inspired by the mind blowing set performed by DJ Tiesto at the 2009 Creamfields music festival. It is used to describe something that is insanely awesome or on its way to being insanely awesome. When on the verge of awesomeness it should be phrased "coming up creamfields" (see similar "coming up milhouse" except "creamfields" is 10x more awesome).
