Skub
A fictional substance of unclear purpose created by webcomic The Perry Bible Fellowship. The comic features "Pro-Skub" and "Anti-Skub" characters fighting each other over their skub affiliation. It is never explained why skub incites such violence, and thus skub has become synonymous with shitstorms, flamewars and NERD RAGE over pointless things. For instance, Warhammer 40,000 and WARMACHINE are oft referred to as "Skubhammer" and "Skubmachine".
