I know exactly the affectation you’re describing, and it is absolutely cringeworthy when it comes from the mouths of American men, who, not all that long ago, mostly spoke like....men.
Men in this country used to speak with a cadence and rhythm that communicated certainty and firmness. When American men spoke, they ended their sentences with definition - not ambiguity or doubt - unless that’s what they intended to convey.
Now, this sing-songy, Valley Girl lilt, seems to be built-in to this millenial/metrosexual/pansyboy dialect that I hear everywhere. I hear guys talking like this, and wonder if they ever hear themselves and compare their girly cooing to how real men speak.
I have a feeling that a lot of the wussies that talk that way, have never had a strong male influence in their lives.
The crooning from hades...
Well, perhaps a good comparison would be with the way God, in the bible, told the Israelites “Do not inquire of other gods.” I.e. the real God would honor their dignity and content them in due time, but the false gods would just seek to make play toys out of them, as they anxiously sucked up. (There’s more to the theology than that, but it struck me as a salient feature.)
Basically the twits are saying: "What you're hearing is the absolute truth, but if I tell you that it is the absolute truth you will be offended at anyone claiming to know anything. So instead I'll couch it in such a way that it seems like merely my considered opinion."
“Now, this sing-songy, Valley Girl lilt, seems to be built-in to this millennial/metrosexual/pansyboy dialect that I hear everywhere.”
I think some young people react with hostility when a man does otherwise.
