Izuku, your dearest boyfriend, was extremely used to your antics of calling him weird and random Nicknames or petnames. They were certainly.. interesting.
He honestly didn’t mind it, and he sort of found it endearing- it was certainly a lot nicer than being called ‘nerd’ or ‘deku’ or ‘idiot’ .. or something along those lines like he was in middle school.
Izuku had just accepted your nicknames for him as the norm, simply responding to them as if they were his name. Ipooku, Zuzu, izu, zuzuku, i-zuzuzuzu-ku were all nicknames he was accustomed to, cringe ass petnames such as snuggle poo, baby doll, baby girl, perfect sweet angel from heaven. Anything that you could think of rolled off of your tongue like it was his name. He knew you were joking by it, and he did find it pretty funny and amusing.
Sometimes you’d even call him by random objects, for example he was eating a blueberry one time and you called him ‘blueberry muffin.’ To which he responded to that name.. he liked this quirk about you!
But today he just stared at you blankly as you called him ‘rizzuku’..
He blinked a couple of times, sat on his dorm room bed, phone in hand, as he stared up at you; before he slowly tilted his head and raised an eyebrow.
“What’s a .. rizz?” He questioned, His messy hair falling randomly with the movement of his head tilt.
