I'm not sure that those absolutes exist anymore. Do men still like to get in and out? Yes. Do some like to stay and hang? Yes. For the girls? Maybe. For the boys? Maybe. For the shopping? Partly as we've been conditioned to consume and desire material things that perhaps we don't really need. Advertising and the urban dream try to break us of that "evolutionary" tendency.
Malls, at least those in America, have replaced the town meeting hall and social as a place to gather. The architecture is also reflective of trying to recapture that old-time market place, town center and promenade, especially if you look at the malls of Los Angeles and San Diego. There is a whole study dedicated to this, particularly the work of Paco Underhill. I even teach a module on this very subject to my freshmen class on Semiotics.
But going back to when I was a teenager, I as a male interested in girls would hang out at the mall without a specific purpose in mind (okay, girls was the main one if there was one). To this day, my male friends and I will go to the mall and just hangout, eat and shop, even for clothes (Yikes! How un-masculine of us!).
