After leaving the office, Peabody feels frustrated by the nicknames being used, particularly the one referring to her as "I'm-Too-Good-to-Pee-Body." She finds it irritating and thinks it reflects poorly on her. This irritation is compounded by a pressing need to use the restroom, which she humorously thinks is a way for her bladder to make a statement about the situation.
Peabody's annoyance leads her to contemplate the absurdity of her situation, even considering making a joke about using the bank for her needs by calling it a 'deposit.' Her inner monologue captures the mix of humor and irritation she feels in response to the nickname and her current predicament.
