First, "joannajet" and "joanna jet" – maybe that's a name or a username. "Me and you" is a common phrase, possibly for a song or a title. The numbers "162" could be significant, like a model number or a count. "Not pus install" – maybe a typo? Could be "not pushed install" or "not published install"? Possibly referring to a software installation that wasn't completed or published.
I knew what that meant. A "pus" install was slang for a "push" installation—the kind where you just click a button and the server does the work. This was different. This required a hand-shake between my terminal and hers, a synchronized dance of code that had to be perfect. joannajet joanna jet me and you 162 not pus install
