デブブの痩せる気なし！あたしもう知らない！デブブなんかもう知らない！
次回ダイエットゴォール！！

I'm not inclined to slim down the chububs! I don't care any more! I don't care about being chububby any more!

Next time: Diet gooooal!!
Here it's a cuter way to say "[i]debu[/i]" (chubby/fat), but "[i]debubu[/i]" mainly comes up as referring to the Debub Region of Eritrea. On the off chance it's deliberate, I tried to combine the two.
