Paper money kept inside a person's sock while they wear it, usually because they either have no pockets to hold it, or it is kept hidden to prevent loss from robbery or theft. The downside is the paper becomes damp with the person's sweat, usually resulting in the money having a bad odor when presented to purchase something.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.
