I was recently browsing WebHostingTalk and I came across this thread;

Why am I posting this here? Because poster #1 is clearly a Forumtard for paying $5 per month for a VPS and not expecting a company to sell. Here is where I am inclined to agree with poster #2.
The Tardforums are now active. Check them out by clicking the button above (it’s labelled TARDFORUMS you baffoon!).
Or click here: boards.forumtards.com
I’m hoping to have the Forumtards forums ready for launch by the end of the week, in time for the weekend. It’s mostly there. Just a few little things to take care of before we can go live such as:
Forum structure
Easy Russian killing methods (spam-prevention)
It’s based on bbpress, so expect something really basic.
I’ve eaten all the jelly beans, now I’m going to bed.
What would you call the Forumtards Forums? (serious question)
When you say you’re gonna stalk me, you better fuckin’ stalk me!

Let’s clear this up, as this is not intended to be something offensive to those who have, amongst other things, Down’s Syndrome. I’d be offended if someone was to refer to someone I knew who had Down’s as a retard.
There is a difference between a Tard and a Retard which is eloquently summed up by Urban Dictionary.
A ‘Tard’ is any person who is not developmentally disabled, but rather has what is considered normal cognitive faculties but for whatever reason has opted out of using it. Whereas mental retardation is genetic in nature, this form of behavior is environmental usually resulting in too much daytime television, Brittany Spears piped in pop music, and other environmental factors.
So yeah, FORUMTARDS is supposed to be offensive, but only to the freaks and idiots we target. Not to anyone else.
