Named after the blog it was hosted on, Walfas refers to Walfie's style from between 2007 and 2013, typically associated with the Touhou art he was drawing at the time. In turn, content generated with the create.swf applet hosted on said blog, created by Walfie with scripting help from Thefre, is also referred to as such. Walfas content can normally be identified by that style, further so if it uses the art from the applet.
This tag is not only for content based on this style (generally created with create.swf), but also for content which parodies or homages Walfas content.
