Dead Weight/Playing With

Basic Trope: A fat zombie
 * Played Straight: Bob is turned into a zombie, who is a little on the portly side.
 * Exaggerated: Bob is disgustingly obese as a zombie
 * Everyone in the Big Fat Future is turned into Dead Weight during a Zombie Apocalypse
 * Downplayed: Bob is Hollywood Pudgy at worst
 * Justified:
 * Bob has been feasting on flesh...and lots of it
 * Bob's zombification process involved putrification, which led to gases building up and making him look bloated.
 * Bob was rather chubby before he became a zombie
 * Bob is a Mook Maker: he is a containment chamber for smaller creatures that spread the infection. (Think the squid things in Halo or the Swarmers in Dead Space.)
 * Inverted: Bob is a very skinny zombie.
 * Subverted: Bob appears no fatter than any other zombies around.
 * Double Subverted: But after eating plenty of Brain Food, he gains a substantial amount of weight
 * Deconstructed:
 * Reconstructed:
 * Parodied:
 * Bob complains about not being able to fit into his now-ragged clothing.
 * A Zombie Apocalypse in a Big Fat Future setting
 * Fat or Hollywood Pudgy zombies are seen attempting to follow a workout video.
 * Lampshaded:
 * Averted:
 * No fat zombies
 * No zombies, period.
 * Enforced:
 * Invoked: Bob's nonstop feasting on flesh causes him to gain weight.
 * Defied: Bob doesn't eat too much and doesn't gain weight.
 * Discussed:
 * Conversed:
 * Played For Laughs: Insert any jokes about fat people here.
 * Played For Drama:
 * Bob is eating everything in his path...and is really hard to destroy.
 * Bob becomes an Action Bomb

You know, you seem to have put on a few pounds since you turned into a zombie...
