look up any word, like bae:
 
1.
The act of dancing with a lady so close that the fabric of her clothes eventually polishes your belt buckle and leads to the eventual embarrassing hard-on also known as a buckle-shiner.
Buckle shine.
Oh shit man I was dancing with this real hot chick last night, we danced so tight that I ended up with a buckle-shiner.
