Rule of Snow 

The rule of snow is the rule that a pretty girl will always look twice as pretty when it's snowing outside.

Usually only happens when the snow is falling softly, not common in blizzards or other similar conditions.

Person A: I already knew Molly was a gorgeous girl but yesterday it was snowing and when I saw her standing outside she took my breath away!
Person B: Gotta love the Rule of Snow.

The Chrissy Snow Syndrome

Generallt occurs only on long-running TV shows, but there are exceptions. When writers accentuate the traits of formerly likable characters in later seasons so that the characters become complete stereotypes. The eponymous Chrissy Snow (Suzanne Somers) on Three's Company was the trailblazer - she came blonder, her do became more implausible, her intelligence level plummeted, and her laugh became unbearable after season 1.

Friends was a fine show until the Chrissy Snow syndrome struck again. Monica became an anorexic, OCD shrew. Ross became a simpering buffoon. Phoebe became - eh, who cares.

zero-g snow 

When a man ejaculates in space and let’s the resulting semen float around in the air for a while.

Captain Jack ejaculated into the crew sleeping area, allowing the rest of the crew to wake up to some zero-g snow.
