Need a regular expression that matches hyphenated words

I need a regular expression to find hyphenated words.  The catch is that some words contain multiple (2 or more) hyphens.  

For example: The cow-jumped-over the lazy moon

I need to match "cow-jumped-over"

Must work for any words that contain 2 or more hyphens.

    I'm not sure whether this is the cleanest way to do it but in perl:
    my $string = "The cow-jumped-over-the the lazy moon";
    my @hyphen-words = $string =~/((?:\w*-+\w*)+)/g

    s/hyphen-words/hyphen_words/ for valid variable name in perl

    The same regex should work in javascript with the RegExp object and PHP
