She’s not. She’s just using that argument to not speak the truth: That it’s disgusting to not keep yourself clean and she’s ashamed of your (probably) poop stained underwear.

Teenagers truly can be disgusting. It’s hard to tell them though. Even harder is, when this applies to grown ups.

Growing up means to realise that even the hurtful thing’s people said to you, where probably just said because they care for you. (Not everyone cares obviously) Parents live their first life too.
