You don't eat dinner in the morning.
Lyric: "I get so high I like to keep her under, fucked her all night so in the morning fed her supper." Song: "I'm On Worldstar"
I get what 2 Chainz is trying to go for here, but even if you missed eating during the normal dinner hours and didn't get the chance to eat until the next morning, that would still be breakfast. Sure, you can eat dinner foods in the morning, but that would just be having dinner for breakfast.
But none of this really matters because the thing you need to take away from this line is that besides being a great lover 2 Chainz is very concerned with his girl's nutrition and that is very nice of him. Thank you 2 Chainz.
