Equivalent exchange?

Ok here is the pun of my day.
I was wearing my full metal alchemist pendent today.
I was with my group for class eventually
Then i got ask what it was and they started guessing odd things like...
medical symbol, cross, cult

Then UM i like said it meant Equivalent exchange lol The trade of life or something like that i said.. :p

Now Im wondering if i should have said cult and explained more about full metal alchemist, choices choices choices...

End
