I realize this isn’t a word. I can think of no X word associated with snow. I even cheated and used a dictionary, thesaurus, and Google. No X word. Even the eskimos have no X word for snow. Please feel free to not count this word as an answer.
I think we can always cheat with some letters like that. After all, we CAN create a layout and emphasize on the X like in “eXtreme”. Why not? It is creative too!
I don’t live in snow country, but don’t skiers sometimes zig zag in the snow? And I think yearning for springtime is something many of us feel right now.
