Literally meaning "to draw a picture" is Japanese, it's become a term amoung artists, usually of the anime sort, to draw on a certain board using either OekakiBBS or PaintBBS and drawing pretty pictures to share with the board buddies.
My friends are better at oekaki than me, but I pwn them once I go onto Photoshop!
An online "board" where people can draw, via a java paint applet, pictures (usually in the style of anime) and can have comments posted by other users, so as to have their artwork thoughtfully critiqued. Fun to do if you go to a good board.
If you don't have a tablet then oekaki boards would suck.
An online drawing website were you can interact with other people. Choose from several programs to draw with. Other users can leave comments on the picture you drew. Can be used with a mouse or a tablet.
I was up all night drawing my 1337 picture on the oekaki
Oh man, my uber gay computer was lagging while I was trying to finish my oekaki, whilst drawing with my tablet
A place to draw, where your pictures usually come out pixillated and overall a little shitty, unless you have a tablet/go to an advanced oekaki. People may comment on them giving their opinions. Oekaki, when translated, means 'scribble' (which is exactly what your picture is).
