Adding "fag" to the end of words is typical chanspeak. There's no actual offence intended at all, most often it's just trolling. If anything it's a good screening process for here too. If people get utterly offended, then they will find it difficult to stay here, if they see it as a joke or shrug it off as nothing, they'll be fine.
Have you've heard of or being to places like Encyclopaedia Dramatica, SomethingAwful and/or 4chan by the way?
