I’ll try this forum…although GQ might also work.

Gaelic Storm has an arrangement of the trad song New York Girls on their latesr CD, Tree. The lyrics make reference to a “flash man”.

What is a “flash man”?

“Flash” is anything or anyone snazzy, sharp, or ostentatious.
As in “Flash car, mate!”

thanks! I wasn’t sure if “flash” was just an adjective, or if “flash man” was a specific kind of trade…
