Random Chat

One of the two most kick ass places on the Mara forums (the other being SPAM Chat). Known as RC by its inhabitants, it's so awesome that members of other forums such as Restricted Chat copy things in it and overuse them long after they've gotten old.
Surprisingly enough, about 90% of the general population of RC is made up of complete idiots. However, these idiots aren't shunned. The members of RC have discovered that idiots provide small amounts of entertainment, and quite gladly let them hang around and make fools of themselves.
Trolls also provide a fair bit of entertainment, as they play out the stupidity of these hapless morons.

RC's biggest downside would be the people that believe they belong there, when in fact, they would be better off under the care of Restricted Chat's 18 year old grannie Jade who will open her arms and shove a dildo up the child's behind at the first welcome. This is how they get accepted.
These tend to be whiny brats that make tags, use lots of emotes or use all caps (or all three) to draw attention to their topic where they complain how unfair there life is because their mom makes them do the dishes.
Not uncommon in this sort of topic is the handing out of cookies, other various foods and drinks, virtual "dancing" and searching for the perfect bf/gf. Thinking they're so rAnDuM!!11! and kewl, they'll bash anyone with a lower post count and suck up to anyone with a higher one in order to gain an imaginary "experienced" status while talking about how they *hits you with a cookie and jumps on llama and rides away*. Yes, they're that stupid.
Otherwise, RC is a great place. Whether you like to actually chat instead of getting fat on imaginary food, or just sit back and laugh at the sheer stupidity of some people, it's a good place to do it
