I find it obnoxious, only because, they don't know what they're saying, it's derogatory toward women, and, it's hypocritical that they can talk about sleeping with a woman and then dumping her (using her), but, get vapors over far more innocuous subjects.
But, it offends me most of all because it's so 60s/70s and it just isn't correct in context. What does it mean when they're taking about clothes?
It offends my correct-usage sensibilities.
