Momcano 

A mom who is also a dormant volcano just taking everyday as it comes without venting or speaking her mind. But somewhere deep inside she feels it coming, the day when she’ll flip out and explode, spewing lava all over the school hallways. Until that day she just smiles.

Carol seems so controlled but you know she's a momcano about to erupt.
