When Courtney takes joy in pouring water on the object of her affection/ boredom's top to make her unwittingly enter into a wet T shirt contest but protests when that same person does/ attempts to do the same to her. That makes her hypocritical.

Disgraced attorney Rudy Giuliani’s face became drenched in sweat and hair dye as he invented evidence of widespread voter fraud during President Trump’s clown coup.

Lily (To Current Partner) : Oh you shouldn't worry about my ex, I don't want to get with him, I feel nothing towards him romantically.

This is being hypocritical
