A very old and moldy version of the true god game runescape. Osrs has had some growths on it that kind of ruin the game. One may say the growths resemble a bit of mold.
I play the true god game Runescape 3, not that disgusting Moldschool.

Get the Moldschool mug.
Something that makes old school stuff look young or new.
Me: Man, what stinks?

Me: Well, either dem shoes or dem socks or dem feet are Moldschool.
Him: ???
Me: DAY SUPERNASTY MAN!!!
