[I went from "jacks" being the game of jacks, to the way you play it -- first you grab one jack during a bounce (onesies), then you grab two in a single bounce (twosies) and so on, and you generally express the highest number you can get to in that way, e.g. "I can get all the way to fivesies!". Trivia of the highest order, and dating from a time before my own, but there's plenty of older culture that I'm familiar with. Meanwhile, I'm still figuring out modern stuff like internet abbreviations (WTF = "Why the Face?" yeah?) and why I have to hear profanities in pop songs.]
[BTW, I'm up to onesies.]
