how to understand "grandma-ed" and "hold her rolls of chub"?
We don't much want to say goodbye to Grandma but mumu looks to me to be a bit 'grandma-ed' out so we cuddle her and I hold her rolls of chub in my hands and breathe in her rose petal smell.

Question

Answer

These are both very strange expressions. I would guess that grandma-ed house means she's tired of acting like a grandmother and needs to stop for a while. Rolls of chub must mean she's fat in a pleasant, soft way that makes it nice to cuddle her.
