Fossyness

To be fossy, from the root word of 'fussy', is to be irritated in a joking manner.

Sara expressed her true fossyness when she tickled Chris for having eaten one of her cookies.

When one wishes to impose a playful frustration, verbally admitting one has become fossy or possess fossyness portrays a humorous irritability within that person.
