Thought process
I first imagined walking into a bar and saying "Gimme a ..." for each one to see which scanned best. Then because I'm sort of alergic to alcohol I tried the same with "light" on the end. Nothing really stood out. However in the same way that a Bloody Mary has a Virgin Mary I reckon the "17 Mile Skydive" could have a "17 Yard Skydive" so plumped for that.
