I don't know man, it's a clear joke rather than an accusation of actual infidelity or wrongdoing. By this logic, can I sue for defamation the 12 year old who calls me a gay slur on Xbox Live if I record the statement?
Well no, because he's 12, he's not doing it in a public forum, and it would be impossible to prove damages.
In this case it's not obvious in the context that he's making a joke
You're not using the same logic there at all. The same logic would be taking out an ad in the Globe and Mail, or putting up a billboard to the same effect. Twitter is not the same as talking to your friends in person, and people should realize that.
