I think you're right about the pasta, but I do not agree about a "station wagon person" having anything to do with jumping on the band wagon. I imagine - although I have never heard the expression before - that it means the sort of person who would drive a station wagon, something like a soccer mom, perhaps?

I've just seen fdmaxey's answer and I think his explanation about "a station wagon person" is much better than mine.

Ah ok...I agree with fdmaxey - I had never heard the expression before - it must be an Americanism...Sorry about that. It makes more sense. In the UK we call don't use "station waggons". We have people carriers (cars usually for those with children) and minibuses (eg hired from a company by businesses/social or sport groups for transportation). I didn't make the connection. Sorry for any confusion!

i am not native, but i think i have come accross the expression "station wagon person" in some reading and following more or less fdmaxey i understood it as a very common person, a nobody or something similar.

Both opinions on the overcooked pasta are correct. However, I think in this case, a "station wagon person" would be someone who looks for usefulness rather than exitement.. Station wagons are not sporty or flashy and they handle like a Sherman tank - their one and only purpose is to get several people from one place to another, having as little fun doing it as possible. In one sense it's positive because someone who buys a station wagon is clearly not trying to impress anybody.
