Any language, explain what it means if it’s not English.
For example (as a non-native speaker) I’ve always liked the English word ‘unprecedented’, mostly in the context of fiction. Especially if it paints some entity to be really mystical or wondrous or it’s own never before seen order of magnitude in any way.
English: Spaghettification (being ripped/stretched apart extremely violently)
Oh and almost forgot: Yeet is an actual word now, so that as well.
German: Zeitgeist (so well known you’ve probably heard it already [“spirit of the times”])
Programming languages: print(“lol, lmao even.”);
