window.location.href contains the current URL of the page.

So your function should look like this:

function twitterShare(){
    window.open('http://twitter.com/intent/tweet?text=Check this out here: ' + window.location.href,
                "twitterWindow", "height=380,width=660,resizable=0,toolbar=0,menubar=0,status=0,location=0,scrollbars=0")
    return false;
}

You can use window.location.href . It holds the value of the current page you are on.
