This works perfectly for what I'm using it for (auto meta description and og:description content for WordPress), but I wonder if there is a way to write it shorter/cleaner:
$content = $post -> post_content;
$content = wp_trim_words($content, 40, '...'); // 40 words
$content = trim(str_replace(' ','',$content));
$content = do_shortcode($content);
$content = html_entity_decode($content);
$content = strip_tags($content);
$content = preg_replace('/\s\s+/', '', $content);

Okay, I think this will do the trick. I wanted to be able to use it again and again and then I thought, hey maybe it's like js. I'm a visual designer in my brain so it takes me sometime to get the hang of this stuff.
function do_meta_description_cab() {
global $post;
$content = $post -> post_content;
$content = wp_trim_words($content, 40, '...'); // 40 words
$content = trim(str_replace(' ','',$content));
$content = do_shortcode($content);
$content = html_entity_decode($content);
$content = strip_tags($content);
$content = preg_replace('/\s\s+/', '', $content);
return $content;
}
//Usage: $content = do_meta_description_cab();
