It's a bit oversimplified, but in fact, what yer buddy told you is accurate... It is the body's *parasympathetic* nervous system kicking in, in response to ingestion of food. By contrast, a *sympathetic* nervous system response would be to, say, get you all hyped up when the klaxon sounds and you go out on a magnum launch to protect your carrier (The classic "fight or flight" response, as many call it...).
