"Sad girl in snow" is a phrase from the webcomic Megatokyo. It has its origins in strip number 75, when Yuki writes Piro (the character) an email telling him that she likes the drawing titled "sad girl in snow." The readers of Megatokyo would probably have forgotten this little mention if Piro (the artist) hadn't titled strip number 123 "sad girl with bear." Alas, the double reference to Piro's love of drawing adorable, vulnerable, underage girls left him open to a fair share of good-natured mockery. Said mockery came in the form of guest strips by fellow webcomic Mac Hall (strips 142 and 209), but Piro went along with the joke when he issued his Halloween death threat to Mac Hall's creators (strip 188). This ongoing joke has yet to reach a solid conclusion.
