Too young for that shit 

Once a person feels the need to avoid a certain event which contains mature content and the likes, such as pornographic and erotics, they have the option to use this excuse. But basically it can be used for anything which the person is too young for, even if they are not young in age.

Person 1: Hey man, wanna watch that erotic movie later at my house?
Person 2: Nah man, I'm too young for that shit. Sorry.

Example 2

Child: Dad, please tell me what you and mom talked about earlier!
Father: Son, I'm sorry but you're too young for that (shit).
