Snow Brain 

A complete and utter mush of your brain as soon as you see snow falling. Full effect happens when at least 2 inches of the white stuff is on the ground and you can play. Snow brain takes over all thoughts and ensures you forget everything you should be doing and forces you to get excited about rolling about in it. Often affects children and diminishes as you get older, but not always. Often affects men more than women. Women equivalent is baby brain.

Look! Look!! It's snowing!!! I'm so excited!!! I can't think of a thing else! I have to go! I have snow brain!

snow-brainer

a no-brainer but in terms of winter-appropriate attire and overall winter safety in northern countries like Russia, Canada, Scandinavia and parts of New England, among others

wearing at least a coat and winter boots, and not just a mini-skirt, is simply a snow-brainer. all this to say to say yesterday i met a girl outside my fav Irish pub wearing nothing but a mini skirt and some tank top, talking on her phone. I asked her if she wasn't cold, and to get a coat, which was also a snow-brainer on my part.

Snowtrain 

when you cover your boner in whip cream and have someone swallow it whole

That girl at the party swallowed my snowtrain.

I tried to put my snowtrain in her butt tunnel but it just made a mess.
