@rotation Which part are you having trouble with?
And you'll never get your fill-a~
@rotation I thought it was, "You'll never get your fill o' / cupcakes".
@rotation The o' being of, like in fillet o' fish.
@rotation Like !tea o'clock. !Tea of the clock. Fill o'cupcakes. Fill of cupcakes.
@rotation To get one's fill of something means you've had enough; you're full, like after a large meal.
