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.

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.
Lily (after breaking up with that current partner the same day) : I kinda want to get back with my ex (the same one mentioned previously)

This is being hypocritical
