"Billions of bilious blue blistering barnacles!"When someone has a particular word or phrase they use as an expletive that isn't otherwise used as an expletive. This is distinct from Goshdang It To Heck, which are Bowdlerizations of commonly accepted swear words. The Unusual Expletive does not stand in for a swear word—the character uses it as a swear word. If a word or a class of words are used as expletives in Real Life, then this trope doesn't apply. That means that all names of gods fall outside the trope's scope, fictional deities or not. This also extends to names of sicknesses, sexual acts, or similar. There must be a sense of originality to the unusual expletive. A kind of Catch-Phrase. If the character uses a foreign word as an expletive, it's a Foreign Cuss Word. The reason to use an unusual expletive can vary. Often, they are used instead of Goshdang It To Heck, like in children's shows where even "darn" can be viewed as offensive, but they can also be used as a way to add character or style to a person or a setting.
