Bad Physics

Bad physics is just what it sounds like: screwing up the way the universe ticks. This can be accomplished by an impossible action performed by a character, or a warping of the world to cater to a character or situation's favor or disfavor.
==By Characters==
===Canon Characters===
At times, canon characters in works of fiction break or bend the laws of physics. Truly, how did Cartman survive being frozen for over five hundred years in "Go God Go"? How did a single rocket manage to fly an adult Orca whale to the moon in "Free Willzyx"? In a wholly realistic work of fiction, it would not be possible - but why is this acceptable?
For one, the rules of the canon are crafted as such to allow them to. Unrealistic feats are acceptable breaks in reality because we want to see them happen... and if they are pulled off well the plot is carried solidly by the audience's suspension of disbelief. Whether by justified skill, innate ability, or just plain dumb luck, we can believe they are able to accomplish these things - and this is the backbone of most fantasy and science fiction.
===By Fanfiction Characters===
A fairly good rule of thumb is that if canon characters follow physics, then so should an original character. If a canon character is an 'Ordinary Thirteen-Year-Old Girl,' she should be able to do all that an ordinary Thirteen-Year-Old Girl can do so far as physics are concerned. If a character breaks the laws of physics, it had better have a very good reason why it's allowed to. There are some continua wacky enough to make physics optional, but otherwise it should not be assumed that anybody is able to make physics act in their favor when it comes to impossible feats.
Fanfiction characters that change physics to survive (not as a superpower, more like 'Because I took middle school blackbelt karate I escaped from his sleeper hold with one swift movement and ended up with my supple thighs snapping his hairy neck') or expect physics to ignore their character are usually Mary Sues.
==By the Setting==
===Canon Setting===
Face it. Ignoring laws of physics and other science facts is what allows us to have cool explosions in space, or giant robots that would otherwise collapse under their own weight. Like the use of magic or super powers in a work of fiction, these breaks from reality are acceptable and very enjoyable. We can believe the giant robot exists in this setting, because that is a rule of the setting: giant robots. In this same way, we can accept things like magic.
===Uncanon Setting===
Physics doesn't care about a story. It doesn't allow something unjustified to happen. In the South Park canon, the laws of physics are slightly different than those in the Real World... say, allowing canon characters to perform feats otherwise impossible. But bullets don't suddenly veer off course to save a character unless magic or superpowers are involved. Objects don't fall sideways. Poor authors sometimes use very, very unacceptable breaks from reality to baby a character or perhaps bash a character by literally turning the rules of the whole world for or against their favor.
This also can be invoked accidentally, if an author is unclear on what they are writing. Vagueness can cause very odd things to happen in the world of a fic, and poor writing in that vein is often the source of much reader frustration.
==Exceptions==
===Humor===
When something is really and truly comedic rather than an unfortunate construction of poor writing, sometimes messing with physics can become acceptable and entertaining rather than charge-worthy.
===Magic/Superpowers/Phenomenon===
It goes without a saying that wizards and some superheroes are able to and allowed to directly mess with the laws of physics. Also, there are some plots that revolve around physics being distorted or played with. Audiences can accept this so long as the reasoning behind them is not nonsensical. This is primarily because these powers are directly mentioned and not a cover-up to make a character seem more awesome or for the world to bend to a character's needs.
===Canonical Null Physics Zones===
While it is generally accepted to follow the laws of physics as they appear in the South Park canon, there are some places in canon where physics may not exist as we know it, and Matt and Trey continually make stuff up. These include spiritual realms, Imaginationland, or similarly weird places where the laws of gravity, momentum, friction, etc., may not apply. In this case, it may be acceptable for a fanfiction author to include wacky depictions of physics in absence of any one real, non-contradictory ruleset to follow.
