Re: people, this is a troll (m)
It was a weird comment anyway because Courtney was a really popular name in Britain in the 90s, up to 17 at one point and only left the top 100 a few years ago, so I doubt it's perceived as an American name by most people.
It's true Britney never caught on but I don't think people here would use the phrase "trailer trash" to describe it. That's an American phrase anyway. Maybe the poster is American, not that I care particularly!
I assumed the poster was just trolling but I just wanted to add that about Courtney.
