22 Amazing Fictional Swear Words Everyone Should Use In Real Life

21. Gimboid (Red Dwarf)

Essentially a stand-in for 'idiot' or 'gimp', and sometimes changed to 'gimbo', gimboid is a favourite insult of Dave Lister, despite being something of a gimboid himself. It's one of those curses that feels ridiculous as you're saying it, lessening its offensive power but making it no less fun to utter.

20. Belgium (Hitchhiker's Guide To The Galaxy)

Originally used in the first BBC radio broadcasts of The Hitchhiker's Guide To The Galaxy, the word 'Belgium' may seem harmless enough to us humans, but that's only because we're too stupid to understand it. Apparently the most appalling word in the universe to everyone but us, Belgium's exact meaning is unclear, but it was used to replace an instance of the word f**k in the American edition of Life, The Universe And Everything, so just watch out who you tell your holiday plans to.

19. Nerfherder (Star Wars)

First hurled at Han Solo by Leia Organa in The Empire Strikes Back, the insulting term is basically the equivalent of calling someone a pig farmer or suggesting that they're way beneath the speak. Well, she is a princess after all. The word has been carried through the Expanded Universe and even into pop culture, with the band responsible for Buffy the Vampire Slayer's theme taking their name after the Lucas-ism.
