Imperative command. "shut your mouth!"

Derived from the French language. "Ferme ta bouche!"

Improved upon by an English scholar in June 2005. "Fermoosh" can be used in exasperation and desperation, executed rapidly and decisively in contrast to its cumbersome French counterpart.
Edward is blabbering on like an idiot.

Michelle is exasperated. She decides to make a rapid, decisive imperative command;

"Fermoosh!" she says.

Edward is immediately silenced and peace is restored.
