Here is a chart for you it is simple and easy to remember:
Stop being such an asshole.
Making the same jokes you made in the 7th Grade, when you are an adult interacting with other adults, generally makes you an asshole. So just stop it. If you don’t we are well within our rights to call you an asshole.
Contrary to what this adolescent “politically incorrect” popular culture might have told you that is not a worthy thing to be.
