I googled, it sounds soooooo fab, what do you use the sombrero for Eric? Apparently its uses are endless - from lime squeezer to salting your drink?
Found this on the net:

A sexual act wherein the male participant mounts the female from behind while wearing a sombrero, firing a pistol into the air, occasionally swigging from a half-full bottle of tequila, and yelling "Yi-yi-yi-yi-yi! Ah-haaaaaaa!" at the top of his lungs.
