Humping
Was going to let our seven year old continue to think “humping” was putting your butt on someone else’s head, until he announced to our neighbor he’d humped his sister “lots of times.”
He was so embarrassed when I told him that teenagers sometimes referred to mating as “humping” … at least they did in my day… and it occurs to me, the kid probably has no idea what “having sex” means, since we always use the term “mate” (thanks Discovery channel.) With the way kids whisper it to one another, like it’s dirty and gross, if he’s heard it, he probably thinks it’s some kind of icky dessert grown-ups eat in secret, made with bug larva.
Our kids call it “making mush”. Only recently did our youngest walk in at an inopportune time to later brag to her brother, “Mom and Dad were making mush–naked!” :S
