Tragedy OR Comedy

Recently I've seen a lot of new fics tagged with both the 'comedy' and 'tragedy' tag. This irks me because the two words are completely contradictory to each other. I'm not saying comedy's can't have sad moments or tragedy's can't have light-hearted moments, but saying your story is both a tragedy and a comedy is false because their can't really be such a thing.

Here's the detention for a 'tragedy':
3. any dramatic or literary composition dealing with serious or sombre themes and ending with disaster
4. (in medieval literature) a literary work in which a great person falls from prosperity to disaster, often through no fault of his own

For a 'comedy':
3. (in classical literature) a play in which the main characters and motive triumph over adversity
4. the humorous aspect of life or of events
5. an amusing event or sequence of events

Having both tags out suggests that your character both does and does not triumph over the adversitary in the story. This is confusing and can lead into an awkward as hell story.

So please listen writers, if you play the story comedicaly, then throw in a random tragedy element, it does not mean you can slap on the tag as well. Either make it a comedy or make it a tragedy, don't make it a train-wreck.
