food baby

informal A large amount of food in one's stomach from having just eaten a big meal, especially when it is protruding (and thus resembles the belly of one who is pregnant). Don't take any pictures right now, my stomach is huge! I totally have a food baby! Don't be fooled by Kim—she's tiny, but she can eat a lot, and then she looks like she has a food baby. There's no way Diana is actually pregnant. That must just be a food baby.
