Evypoo on "Editing the Loop to Exclude a Tag"

Hello,

I am having some trouble editing my WP homepage loop. Currently, I have a custom post type called woo_video and on my homepage it shows my latest 9 video posts. However, I would like to add the ability to an exclude a video I post from the homepage (perhaps by tagging it something like "skip home"). However, I would still like it to show in the video categories that it was placed in. My code is as follows:

<!-- Start the Loop. -->
 <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
 			<!-- PHP Post Code Below. -->

 			<?php
 	echo '<div class="home-videos">';

 			$args = array( 'post_type' => 'woo_video', 'posts_per_page' => 9 );
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post();

	echo '<div class="home-post">';
	echo '<div class="home-post-thumbnail">';

	if ( $woo_options['woo_post_content'] != 'content' ) {
	                		echo '<a href="' . get_permalink( get_the_ID() ) . '" rel="bookmark" title="' . the_title_attribute( array( 'echo' => 0 ) ) . '">' . woo_image_vimeo('meta=' . the_title_attribute( array( 'echo' => 0 ) ) . '&width=310&height=' . $woo_options['woo_thumb_h'] . '&class=thumbnail&link=img&return=true') . '</a>';
	                	}
	echo '</div>';

	echo '<div class="home-post-title">';
	echo get_the_title($ID);
	echo '</div>';
	echo '</div>';

endwhile;

	echo '</div>';
	        ?>

 			<!-- End the Loop. -->
 <?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>
            <!-- End. -->

It is probably an easy fix but I can't seem to get it to work. I appreciate your help!

Thank you!
