...because, just as with your edit to Downplayed Trope cited below, it is lifted word-for-word from TV Tropes. As noted below, this is copyright infringement and illegal.
Strictly speaking, by the terms of All The Tropes:How We Do Bans Around Here, this would justify imposing an immediate tempban on you, but given that both infractions were only detected today, and this notice below was only delivered after the second instance of infringement (and you have three more unreviewed edits in the moderation queue which may have additional infringements), in the interest of fairness we are only delivering a formal warning here. If in a future edit (submitted after this message is posted to your user talk page) contains another instance of copyright infringement, you will be subject to a tempban of at least two weeks' duration.
Please acknowledge receipt of this warning in a message in this thread. No other means of contacting moderation staff will be accepted, and failure to acknowledge this warning while still submitting edits to the mod queue will also result in a tempban.

EDIT: Your proposed edit to "Played for Drama" has also been rejected as infringement.
