I'm not sure. We could say thingys like 'slemslempike her journal' (or 'their' if you prefer), although I'm not sure that that theory is still current. Alternatively we could strew 'y'ys randomly across the commentys and write 'slemslempike'ys journal'. Which would you (would'st thou?) prefer?

Ordering drinkys would be fun. "That's three pintys of bitter, two lagerys, four white wineys - that's small glassys - and two rumys and coke." "That's twenty-three poundys and thirteen pence, please. Ice and lemonys?"
