This is kind of normal and increases as the number of people in the meeting increase. You have options, sometimes I'm very keen to understand every detail of what is being said but that can cause a lot of annoyance for the other people involved. Maybe arrange a private meeting 1:1 with one of the guys you don't understand and ask him to take you through his thinking. Sometimes you can let it go and just concentrate on the task in hand (which may only be a small part of the overall discussion). Once people have a history with a business/product/process, things can get greatly extended, but not always for the right reasons.
