In any language, any one of us has certain words or phrases they like to say.
For me, in English, that includes “bedazzled” and “thingamagick” among others.
Howrver, is there some kind of overarching expression for these words? I can’t think of anything in English or my native German, and a quick Internet search didn’t find anything.
I don’t speak Spanish but I love the word “El sacapuntas” which sounds like a bad word but means pencil sharpener.
