Sacred means a lot of different things to different people. Soccer players might consider their winning cleats sacred. Baseball players, their favorite bat. Boxers, a pair of shorts, or gloves. Basketball players, a certain shirt they wore for a championship game. Then you have chefs and their set of knives, or gamblers with lucky dice. You might think these are superstitions, but just try keeping these winners from their favorite item.  
I wrote a different post on this word, involving religion with a skewed, I admit, attitude, so this time I decided on the LITE approach. No reference to regular or lite beer intended. 😯
