A phrase commonly spoken by folks who have no idea whether the network actually really sucks, or whether their failure to use their computer and/or the network is a reflection upon themselves.
Typically, this phrase is uttered by someone who would also say, "can't you just press a button to make it work?" These are usually folks who just don't get it -- folks who believe that complex systems are produced by "playing with the computer".
This phrase is definitely related to some childrens' impulse to stick their tongue at an innocent dog, wiggle their fingers in your ears, and yell at it -- to prove that they're not scared. So, yes, this phrase is usually uttered by complete and utter technophobes who are being brashly belligerent to avoid admitting that they have no idea what the hell is going on.
That is all.
