The reason he was an asshole is because he tried to kiss her with a bullshit trick/scheme, a weasel act.
But the picture was straight “boys fun” as in Greek Life in college, which being an actual Greek myself I find ludicrous and insulting, and have never met an ass who was part of one of those that I liked.
I never understood why they exist and have to do with Greek “Life”.
WTF is THAT?
I did enjoy the movie, though, with Belushi.
