There's a natural uplift lilt when I hear Irish speak, too, which is not at all like what BillD and AllanC have spoken of with young girls. Of course, Australia and Canada have their share of those from the "auld" countries, so it stands ot reason, I guess, that such things might cross over.:-)

When I was a teen, I think every other word out of my mouth was "man." Drove one of my sisters nuts. We argued about it a few times. "No way" was also very popular. I had one friend whose surname was Nation. She used "no way" so much, my then-spouse called her "No way Nation, shape or form!"
