Nai Nai 

When you're so unhealthily obsessed with food to the point that you are mentally, cognitively and possibly even physically unable to hold a decent conversation about literally anything else. Yet despite all this you don't eat a lot on a daily basis.

Family: (Minding their own business)

A somehow popular phrase said by Gold Experience Requiem (Giorno Giovanna's requiem stand) after activating it's ability "Return to zero" while Diavolo was erasing time, translates to: "You will never reach truth"
The phrase is usually used only as a reference but sometimes it can be used to hide something that you know from others, jojo fans or not.

Person B: Shinjitsu ni tōtatsu suru koto wa kesshite nai!
