No, that’s pretty much it, although it’s more a general bad taste dig, than tourist specific. It’s a variation on the “…buying your clothes at…” Morgan Memorial/ Wal-Mart/K-Mart/whatever is considered low end where you live insult.
The chowder thing I can only guess at. If you were wearing pants they considered inadequately long, it could have been a “high waters” or “clam diggers” (which are really the same thing)reference.
I’ll also add a bit to what ** Davebear ** mentioned above. Whenever one loses their suitcase at an airport, they probably have a tendency to just buy whatever is at arms reach or whatever is for sale at low prices. And so these ‘emergency’ clothes are likely to clash and make you look like you have absolutely no taste in fashion whatsoever.
That’s my take. Nice insult, though. I’m sure you wouldn’t mind if I borrow it, coz I happen to have a friend who makes a brilliant target, lol
Feel free to use it, but I now declair the copyright and all subsidiary interests (public and private) in that line. Hell, “Dude, where’s my car?” is now a valuable franchise. If I ever see “Stop buying your clothes at the airport” in a script title, someone will be hurting.
