For the actual pattern, go here.
OMG TEH EPICNESS is the old technique that was used in the Epicness pattern (referring to the "OMG TEH EPICNESS" spinning text appearing in Sparta Remixes).
This method was so much popular before the 2015 era when this method started to disappear.
In older remixes (2009-2013), the Epicness pattern was usually accompanied by a spinning text reading "OMG TEH EPICNESS". But in the modern era, the spinning text method started to disappear in most modern remixes.
