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.

Mate 1: Hey, I'd be careful risking all that money on one bet. Only risk what you can afford to lose.
Mate 2: Thanks. VSA

The dope dealer thinks he/she knows better than anyone who should be in rehab, then tells other people not to judge. What's more hypocritical than that?

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
