I think Roosh nailed it when he said the best defense to a cockblocker is to embarrass women so much they never do it again. If ugly friend wants to do it she will. I have seen drag aways, fake dramas and my favourite is talking to a girl at the bar when the friend comes up and just pushes between the teo of you then turns her back. At this point you can either walk around and wait for the next cockblock or just announce loudly that one girl is nice but shame about her rude fat friend.
