Some phrase remains fixed in the memory of a family for whatever reasons. “Tu dormi e kinglax lavora” (while you sleep, kinglax is working (for you)) was one that my father liked a lot. Searching in google it seems that it comes from an old advertisement for a laxative, I always thought it referred to a washing machine.
He also was repeating when coming back from work: “Tutte le luci accese!” (All lights on) a costumary plea for energy saving.
I already mentioned zia Sitta’s “ti do una cosa” (I’ll give you a something) or “Nix palix” (nothing).
Not sure if in our present family we have similar idioms, I rather go back to childhood. But sometimes I repeat those.
