Question mark
The rhetorical question mark or percontation point was invented by Henry Denham in the 1580s and was used at the end of a rhetorical question; however, its use died out in the 17th century. It was later revived in modern-day society by Matt DiRoberto. It was the reverse of an ordinary question mark, so that instead of the main opening pointing back into the sentence, it opened away from it. This character can be represented using the reversed question mark (⸮) found in Unicode as U+2E2E. The percontation point is analogous to the irony mark, but those are even more rarely seen.
Rock the Slut Vote
Rock the Slut Vote is a registered trademark that was issued on January 22, 2013 by the United States Patent and Trademark Office (USPTO) to Susan MacMillan Emry. Emry applied for the trademark to use as part of a feminist public relations campaign centering on American politics and voting. The name originated from a remark made by conservative commentator, Rush Limbaugh, who called Georgetown University law student Sandra Fluke a "slut" after she testified in favor of contraceptives at a Congressional hearing in February, 2012. In interviews with journalists, Emry states that "she chose to brand the site with the derogatory term in an effort to take it back and turn it into a rallying cry" and that she had not previously been politically engaged. Emry was inspired by an article in Huffington Post written by Morra Aarons-Mele entitled "Getting Out the Slut Vote in 2012."
