The operating system* little boys employ in a vain attempt to appear computer-savvy due it's perceived complexity, which is really just a convoluted user interface stemming from the lack of higher cognitive ability found in Loonux 'programmers'.
As with any underdog**, you will find a horde of fumbling zealots defending Loonux, who, rather than pose arguments with a rational and verifiable basis, will simply parrot ignorant statements against the operating system(s) that put Loonux to shame (e.g, Windows). More often than not, these lower beings will resort to childish name-calling and irrelevant technical references which further compacts their own ineptitude.
* "Linux" as referred to here is of it's derivatives based on the Linux kernel.
** Windows currently holds 94.3% market share vs Linux's < 1% (As of May, 2009)
