OK kids, get out your thinking caps.

I have a movie trivia question and I'm stumped. I've searched LJ but can't seem to find a good movie trivia community (hmmm ... maybe it's time to start one), so I'm gonna have to post this here and hope that someone who reads my page will have an answer.

Here goes:

There was a movie in the late 1970s or early 1980s. It was a comedy, and the basic premise was that some guy (or maybe two guys?) accidentally rips out the butt of his jeans while he's out in public (by sitting on wet paint? I forget). He's mortified, but somehow people see the jeans, think they're cool, and it becomes the hot, new fad.

OK, so who knows what this movie was called? unixd0rk and I spent far too long googling various plot points but finding nothing. I think it was a one word title -- something like "Divine" -- but my searches of IMDb have turned up nothing.

Anyone?
