As I am sure the reader is aware, roflcopter is way of enhancing the leet quality of the simple rofl. Omgcopter is the same thing but with omg
leetxorz
As mentioned in lolxorz, the suffix xorz is substantially more leet than the plainer zorz. So when expressing admiration or amazement, trump the simple leetzorz with the leeter leetxorz.
roarxorz
