Yeah, by modern standards, it’s rapey and cringe. The entire song is a guy trying to get in a girl’s pants while she’s repeatedly telling him no. It’s ambiguous what her real feelings are, whether she is a willing participant in this cat-and-mouse game, which I guess is part of the fun, but his are unmistakable.
How about that line about “what’s in this drink”? I don’t know if there were date rape drugs back then, but there certainly are now, and the use of them is absolutely disgusting.
I’m sure Dean was a popular fellow, but no, being attractive and successful doesn’t mean you are entitled to get into any girl’s pants, and making songs that model that sort of behavior is problematic.
I imagine it was an acceptable song for its time, but we’ve come a long way since. It’s understood now that women have their own independence and can choose their partners and they aren’t passive asexual robots to be broken down through pressure into finally coughing up sex.
