With multiple threads about triskaidekaphobia, many are still unaware of criscodeckaphobia. It's the fear that the cook will spill grease on deck and make it slippery. Like that line from "The Wreck Of The Edmund Fitgerald...

When supper time came the old cook came on deck
Saying fellows it's too rough to feed ya
At 7PM a main hatchway caved in
From the weight of many sailors on high-fat diets.

(that was Lightfoot's first draft. That was before Gordon Lightfoot renamed himself "Gordon Lightfood" and started campaigning throughout Canada for better dietary practices.)
