The Mechanics, reduced to the absolute basics, go something like this: Tab A inserted into Slot B, coupled with suitable manipulation of Button C. Unless you're a dinosaur, in which case you lack not only Button C but also a fully formed Tab A (and your Slot B is in fact an orifice of a nature entirely different from that which badficcers are used to), and so should not be attempting anything that may later warrant inclusion on this page. Many badficcers have precious little knowledge of the Mechanics. This leads to charges such as bad biology, dubious lube, and squick.
