If you’ve watched any, I suspect you’ll know what I mean. There’s a very specific laugh that female characters may do, often while contemplating some kind of victory. It’s sort of like, “Oh - ho - ho - ho - ho!”.
Anyway, what’s the reason for this being so common? Is there a particular person who laughed like that or a series it’s referring to? Is it a homage? It’s such a specific type of laugh that there must be some common background.
Anime has several standardised sounds characters can make to indicate stuff, that you’ll probably never hear in real life.
O-ho-ho-ho - Superiority complex laugh
Mu-fu-fu-fu - Secretive/plotting laugh
Kiiiiiiii! - Superior girl’s mad sound
-zamasu - Ending a sentence with -zamasu indicates a sort of middle-aged annoying cow-like shopping woman
-dawaaaaa - Superior girl sentence ending when she’s happy and/or showing off
(Just as a sample)
No real idea where a lot of them came from–though I presume that they were taken as riffs on someone annoying at some point and then adopted by actors or screenplay writers and then spread.
Anime acting isn’t Method Acting. Particular if a scene or character is meant to be humorous, they’re fine to use set gags and stereotypes, and subsequently there’s a whole swath of set jokes and characterizations.
