What is the word/expression when you take pleasure in doing something that convention says you are not supposed to do?

What is another way of saying when you take pleasure in doing something that convention says you are not supposed to do ? (ie the word or expression that I am looking for is very similar to saying for example, I take "subversive pleasure" in talking loudly in the library. I am not thinking of "perverse pleasure", though that is an equally good synonym, its just not the one that I can't think of.)

Solution 1:

Guilty Pleasure.

You'll see uses everywhere, from food you enjoy even though it is bad for you, to music you enjoy even though Justin Bieber sings it.

There is a related question online that suggests indulgence or perversion, which meet the single word criterion.

Solution 2:

Consider transgressive pleasure

"Transgressive" definition: going beyond acceptable boundaries of taste, convention, or the law.

Example: consecrating innocence, the modern mythology of childhood ascribes to children a specially rampant natural appetite for all kinds of transgressive pleasures, including above all the sado-masochistic thrills of fear.

Solution 3:

Another expression for the behavior you describe is a little rebellion. The term is used to describe a person's behavior that deliberately breaks established social conventions or rules, usually in some harmless way that often has more to do with the person's desire to show defiance or nonconformity than the convention or rule itself.

Here's an example:

The director closed the doors as he left. Gab inched closer to his friend, reluctant to stand beside the coffin. When he did, he noticed they had put Pal in a bright red tie, which he would have hated. Pal never wore ties, even to important functions. It was one of his little rebellions against society, Gab speculated.
