While both young men and young women celebrate their Sweet 16 today, sweet 16 traditions such as the candle ceremony, father-daughter dance, passing of heirlooms and the shoe ceremony are typically reserved for young women.
I never heard of boys celebrating sweet 16, it's usually a girls thing. mostly just an excuse to get some presents/cash from parents and relatives, and then head out and find someone 21+ who will buy booze for you and proceed to get drunk (and/or laid). and maybe the spare set of keys to the family car.
@beiser , @blockhead and @boxedjoy there are too many new people with short names beginning with a small b and it's quite confusing so we'll have to assign new names like we did with gus and stan. @luka will follow up in due course
