Yes, indeed, 'Randy' means something innocuous in America, and
that was just my point. If we're to lower ourselves to the lowest
internationally and interculturally neutral denominator, then we
must purge nicknames like 'Randy' from American parlance, lest
a Brit overhear and misunderstand, terms like 'spotted dick' from
British parlance lest a Yank misconstrue and so on.

We thus all get reduced to a common shade of graey.
