Initials

I am bored at work today and got to thinking about Chris Sims Tattoo. When is it acceptable to have another male's initials tattooed on a part of your body? Here is the list I came up with, although the first two were from that thread.

If you each saved each other's lives after fighting off two gigantic killer bears. (from trot)
If one died in a horrible car or plane accident, or was mauled by a rabid ferret. (from GoHorns)
If it is your son.
If it is either a dead relative or a dead "brother" i.e. very close personal friend.
If they donated an organ to save your life.
If you lost a bet (in which case they should probably be on your ass).
If you are someone's prison bitch.
If your wife or girlfriend has a sex change operation. (although this is only a short term solution, you must end this relationship and schedule to have it removed or you fall under the last circumstance).
If the initials are "VY" (although in two years we will probably have to include "JC" and I don't mean the messiah- well at least not that one, but that would probably be OK too).
If you are gay.
