Exaggerated: Every time we see Bob eating, it's from a large slab of meat.
Downplayed: Bob enjoys steak, but he eats fruits and vegetables as well.
When Bob was young, his mother made remarkably exquisite steak and that turned him on to meat for life.
Bob's parents were strict vegans, and meat was a rare treat when his family wasn't present. Now that he's on his own, he can stuff himself with flesh any time he wants.
Inverted: Bob is vegetarian/vegan, while Camp Gay Charles loves meat.
Gender Inverted: Alice loves to eat steak.
Bob announces how hungry he is, and then eats a salad at lunch.
Bob and his fellow bikers walk into a diner and order salads.
Double Subverted: But the salad has bacon and chicken in it.
Parodied: Bob eats nothing but meat, subscribes to a meat-lover's magazine, is on a first-name basis with the local butcher, worships a T-bone steak, and lives in a house made of meat. Oh, and his wife wearsa dress made of such.
Zig Zagged: ???
Averted: Bob's diet is "normal" and he has no clear favorite food.
Enforced: "We need to show that our character is manly. Real men don't eat salad."
Lampshaded: "Bob sure loves his steak." "Come to think of it, has he ever eaten anything but meat?"
Bob believes that a meat-based diet is morally wrong and/or unhealthy, so he makes it a veggie burger with veggie bacon and soy cheese.
"Real men don't give themselves scurvy."
Discussed: "Bob is one manly man. He probably eats nothing but meat."
Conversed: "He should see a nutritionist. An all-meat diet can't be healthy."
Implied: Bob is often shown eating various meats, but never mentions his particular love of them.
Deconstructed: Bob almost never consumes anything vegetarian or vegan, and as a result gets little of the beneficial nutrients provided by fruits and vegetables. His health declines dramatically as a result.
