If you want it to original, I suggest you don't ask a gaming forum, ahaha. No offense. It should be from your heart. No matter how corny that sounds. :p
I used to call my ex, "Ma tout" and she would call me, "Mon tout"; both are French for, "My Everything". And we were both taking French, so I figured it worked out alright. Just take some time to think about it. If you think of one, but you think it sounds bad, don't shut it down immediately... try again in a different language.
But remember, google translator isn't always accurate.
Good luck! :bro:
