In a little bind here - the joke is that Ooyodo says that today's the day for bottles and cans - /binkan/ (As in /bin/ 'bottles' and /kan/ 'cans'), and that Iowa parses that as /binkan/ 'sensitive' (like sensitive skin), presumably in the lewd shenanigan OoyodoAkashi sandwich sense.
But I can't, for the life of me, think of a way to make that work without straying too far from 'sensitive', such as 'cans and bottles' to 'canes and bottoms' or something to keep the lewdness factor intact. If anyone has a good idea, feel free.
It's the same sensitive as sensitive skin, meaning that if it's your 'sensitive day' and you're going on about how they forgot that, it probably means that they were too rough under the sheets, I guess?
