Getting out of the way when someone's coming towards you...

I've been reading the posts on here about what to do if you're paddling out and someone is riding a wave towards you. I have often found this to be a problem, particularly since I'm not great at paddling and manouvering my board.
When you guys say 'head to the whitewater' what do you mean?
Do you mean I should turn around and head back to the beach? Surely that would take more time. I ride a 7'6 so duckdiving isn't really an option.
I don't mean to be a dumbass, I'd just like someone to explain it in real laymans terms so I can stop getting in people's way, because I know myself what a pain in the ass it is!
Thanks guys
