Tequila suicide is a new stupid fad which came from the north of Europe. It consists in using the regular ingredients that you use for a tequila shot, which means lemon, salt and tequila, but in a different way: first you put some salt on your hand, but instead of licking it, you snort it, after that you drink the shot of tequila and then you squeeze the lemon on your eye. In some versions, the last step is to smack the head on the table, but this is just an option. The effects of "drinking" a tequila suicide can include eye irritation (that can degenerate in bigger problems) and nose bleeding.
