I use it as a term of affection for those of us Americans who are 20-something or 30-somethings who decided to latch onto the British Invasion some time in the 1980s and become bigger experts on that era's music than those who lived in it.

I co-own a record label with Chad & Jeremy (they were big in the states), and I can't count the times that one of them has called me and asked "when did I do 'x'?". Many of us of my age became big-time mix maniacs, hunters of obscure old records (prior to the big CD reissues of the last decade) and a bit snobbish when it came to the music our friends were listening to.

I am unabashedly snobbish about the 1960s in general compared to much of the music made from the late 1970s onward. We 'British Invasion Snobs' end up turning our nose up at the newer stuff, while listening to every little scrap of obscure 1960s stuff, regardless of occasional iffy-ability/talent. It's just "better" to me somehow. Even the recording and mixing equipment has a "warmer" quality compared to the harsh sounds of digital recording.

IMHO, of course.
