One of the most endearing aspects of the long-since-concluded animated series Wander Over Yonder was the series' obvious desire to use curse words and strong language. Honestly, doing so makes sense - The show's primary dynamic hinges entirely upon striking a stark contrast between series protagonist Wander's pollyanna optimism and unnatural politeness with the overtly violent and short-tempered Sylvia Zbornak. While Wander himself can scarcely utter even a vaguely mean word, Sylvia is one of the most foul-mouthed creatures in the galaxy, and the fact that they are lifelong friends despite is the lynchpin theme of the series.
But how do you make a character curse a blue streak that'd make a Twitch streamer blush, when your cartoon is aimed at a younger audience, and of course, a property of Disney?
Answer: You make your own swears.
The Obvious Swears
The following is a list of words deployed through the run of Wander Over Yonder that obviously carry the strength and meaning of foul language within the Wander Universe. While true definitions are never given for any term, it is possible to determine which words are swears from the manner in which they are deployed - and the reaction that they sometimes incur.
The following is an informal list of those terms, followed by my best guess at what each term's relative meaning or closest real-world analogue might be.
Grop: Not a swear in and of itself, per se, but apparently the name of a deity which can be invoked. For example, "For Grop's Sake" or "Good Grop!"
Glorn: Similar to Grop, appears to be the name of a deity often evoked for effect. Most common use, "Glorn Almighty!"
Flab drassit: Strong epithet of some variety. Can be used as an interjection to express consternation, a la "Consarnit!" or "Dag nabbit!". "Flab drassit!" can additionally be used to modify other terms, as in, "You flab drassin' frood!"
Hamspangler: Actual meaning unknown, but clearly a derisive noun of some variety. Typically paired with other terms. Example, "Flab crabbin' hamspangler!"
Flarp: Strong interjection, typically modified as "Flarpin'". This term is very likely to be the Wander Universe's F-bomb. Example, "That flarpin' idiot!"
Flarf: Either a softer, or a stronger, version of "Flarp". Context makes this unclear, but one can imply that flarf is a weaker version of flarp based on mouthfeel. Uses include "Flarf Narbler" and "You scared the Flarf out of me!"
Frood: While obviously a nod to the Hitchhiker's Guide To The Galaxy, in the Wander Universe "Frood" seems to be a term for a rapscallion or other type of ne'er-do-well. Often used in conjunction with "Narfin'", a la, "You narfin' frood!"
Miscellaneous/Uncategorized:
The following terms are either challenging to fully pin down due to lack of context, or else difficult to derive due to their scarce deployment throughout the series. They are presented here without attempts to define them, but within their original quotations from the show.
Lupsork: "Are you out of your flip pickin' lupsork?"
Zrebtank: "Oh, Zrebtank" (said with dismay)
Glorf: "You flab drassin' glorf!"
Grofflezop: "You stinkin' glofflezop"
