Pop culture tends to coin new terms and phrases all the time. And the internet, with its daily blogs and news and whatever, they have to come up with new things to say to keep people interested. Kind of like me posting now…
I saw an article that used the term “unsolicited advances” in the title, and it totally sounds legit on first pass. But unsolicited implies there are also solicited. That means you would be asking someone to ask you out. Which is kind of like asking someone out. Which is an unsolicited advance. I think it was just a hasty article. Maybe they meant to put unwanted advance? Or unwanted sexual advance. But whatever word count issue tripped them up. I just thought it was funny.
