This was inspired by an online gamer from Second Life named "Christoph", who was the leader of a neo-nazi organization. Christoph is a furry, who also went under the alias of Snowmew, and later Delrith in the hit FPS shooter PlanetSide 2. The phenomenon became popular when a video came out on YouTube, where another furry from Second Life recorded themselves having a phone conversation with Christoph/Snowmew/Delrith, in which Snowmew wanked himself off to the conversation, in effect having phonesex.
Snowmew is now a widely known phenomenon among the players of Second Life and PlanetSide 2, and catch phrases such as "I grin and nibble your chin" and "I'm a stressed snow kitty" are now common.
"Delrith is actually Snowmew from Second Life!"
Me: "Hey, did you see that vdieo 'The Everlasting Snowmew'?"
Friend: "Yeah, that was some sick stuff - I grin and nibble your chin" ;)
