The sound of a full can of beer (or soda) falling from the second row up. This occurs when you pull an unopened can out from a 12 or 18 pack that has been placed on its side. The sound of a seven slam down is one of the beautiful in the world. It tells you that no matter how bad your day was, you're dealing with at least another 84 ounces of escape. (The beer you grabbed plus the 6+ left in the box)
Unsure of how much beer was left in the box when he grabbed a fresh one, Mike was relieved to hear the soothing thud of a seven slam down.

2. To play a trump card.

Based on a stand-up comedy routine by Dane Cook in which an escalating customer service situation at a fast food restaurant is abruptly ended by use of the term "Gaylord"
Chase and I were having a stupid fight at the nursery over which variety of orchid to buy, so I had to slam down the G.L.
