You've obviously never been married, like I said, in the moment an insult to your wife and especially something as grievous as "You're wife's a fucking slut and the kid ain't yours" is straight up fighting language. Quite frankly a teenager should have had his ass kicked a time or two by the time he reaches that age anyways and learned what is and isn't okay to say.
The reason I laugh at Geoff isn't that feeling of wanting to cave that guy's skull in, it's the combined facts that he's still dwelling over it years after the fact, literally crying over it like a little bitch, doing this crying in front of a camera, and then allowing that to be uploaded for not only RT's audience of millions of people but for the entire world to see because it's on the internet.
