Here is a quotation that answers your question:
"The usual answer is hushion, a rather unusual Scots dialect word for a footless stocking (a sort of leg-warmer).
A rather better-known Scots word is fushion, meaning `spirit, energy, gumption' or (in referring to food) `wholesomeness'.
Neither word is in standard use outside Scotland.
The complete Oxford English Dictionary also lists the word parishion meaning the same as `parishioner' (a member or inhabitant of a parish). However, this word died out in the 16th century without ever settling into a consistent spelling."
