The act of catching a live opossum, then proceeding to slam it into a solid object. The tail is usually used as a point of leverage to incapacitate the animal.
Last night me and my buddy where board so we went up to my barn to go opossum slamming and there was an opossum sitting in the barn so i grabbed it by the tail and slammed it into my oak tree repeatedly. Later on I had a nice BBQ...
