Barnstorming on an Invisible Segway

I am thinking of a time a few years ago with a teen I know. She got called a particular unfamiliar epithet at school, so when she got home, she and her stepmother looked it up. Their reaction was, "Ack ack ack!" that the classmate in question was thinking of this particular sexual maneuver with my young friend. My reaction was, "Honey, you now know for a fact that $classmate is not having the actual sex. Because that's the sort of fancy thing that is probably possible for a small number of people and is probably a very very tiny number of people's major kink. But for the most part it's the sort of thing that sounds awesome when you are interested in bragging about how badass you are at something you've never done, and vanishingly few people ever do it."
