"Whose Durf? Oh he's just some guy I met on some dating service, no need to be jealous honey, come on, it's completely platonic. Damnit we just went out for dinner, we've gone over this a thousand times!"
Luckily its very easy to give the minimum amount of information when talking to people. Of course it is rather difficult to explain where my growing supply of weird links are coming from (and over half of them are from Durf alone).
