Retrieve single term slug

Thank you guys for such quick response. Much appreciated!

Here is code for “global” Tags page (displaying terms of default ‘post_tag’ taxonomy):

<?php
$term_slug = get_queried_object()->slug;
    if ( !$term_slug )
    return;
    else  
$loop = new WP_Query( array( 'post_type' => 'any', 'tag' => $term_slug, 'posts_per_page' => 10 ) );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
  <div class="entry-content">
    <?php the_excerpt(); ?>
  </div><!-- .entry-content -->
<?php endwhile; // End the loop. ?>  

And the next code example is for custom taxonomy query (displaying terms of custom taxonomy):

<?php 
//http://codex.wordpress.org/Function_Reference/WP_Query#Taxonomy_Parameters
$term_slug = get_queried_object()->slug;
        if ( !$term_slug )
        return;
        else
$args = array(
    'tax_query' => array(
                     array(
                       'taxonomy' => 'gallery_category',
                       'field' => 'slug',
                       'terms' => $term_slug,
                       'posts_per_page' => 10
                     )
                   )
);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
  <div class="entry-content">
    <?php the_excerpt(); ?>
  </div><!-- .entry-content -->
<?php endwhile; // End the loop. ?>
