In Mafalda, an angry mother is so angry that she starts dropping vowels and entire words, and as such starts yelling only isolated words. The quote below does not mean anything: she's dropped so many vowels that it's been rendered complete nonsense. In parentheses is the intended meaning as translated by Mafalda.
Raquel: ¡Sunescán! ¡Dalúna buso! ("¡Es un escándalo, un abuso!" meaning "It's a scandal, an abuse!" uttered by an angry mother coming back from market).
The quote above can be rendered intelligible if read with typical Argentinian intonation.
And even more so if you go to the market in Argentina when the prices are rising.
Captain Haddock in the Tintin books often unleashes a tirade of disjointed insults and random words at the subject of his anger.
In one The Simpsons comic book, Homer is seen slamming into Skinner's office when Bart's in trouble, saying "Too angry to finish sentence I-!"
In another story, he tries to put up wallpaper. Hilarity Ensues, of course, and each Epic Fail has Homer cursing more and more, until he runs out of English swear words until he's forced to swear in Chinese.
A darker version occurs in the post-One Year LaterSuperman story arc, "Up, Up and Away". Big Blue has just destroyed Lex Luthor's latest scheme and, powerless, miles above Metropolis, the two are sent plummeting to the ground. Despite giving an impressive speech moments beforehand, as they fall Luthor can only stare at Supes and growl:
Lex: I hate you. God Ihate you.
The DM in Knights Of The Dinner Table will, when exasperated at the unorthodox behavior of his players, frequently be reduced to shouting "FIRK DING BLAST!"
In Tintin The Castafiore Emerald, when Captain Haddock receives a phone call from Thompson and Thomson congratulating him over his Tabloid Melodrama reported engagement to Castafiore, he lets out a series of inarticulate angry syllables before slamming the receiver down.
Incredible Hulk would seem to be the living distillation of this trope. Whenever Bruce Banner gets angry enough, he manifests as the incarnation of Angrish. "RRAAAAARRGH! HULK SMASH! AAAARRRGH!"
