Doesn't talk about boobies and cheetos sort of belong to wibbles?

I mean, i hardly see the distinction. Cars topic could go in discussion, on the other hand. As could movies topic.

Well maybe the cheetos and boobies were a bit on the side of the subject here :P

It's just that i.e. car topics tend to go into "ok here's a nice car i'm gonna post a picture of it and then not care about this thread whatsoever again".

That is not a good discussion topic. I can see how movies could be nice enough as discussion topics but only if it revolves around specific movies. If it's named "what's your favourite movie?" though, it's inappropriate for Discussion.
