Curse to lose my armor with the biggest bonus

[MunchkinMan]

Of the 27 Curse cards in Munchkin Booty and Jump The Shark, there are only two Curses that come close to what you describe: Curse! Scuppered!, which says to lose the Item (not Armor, specifically) that gives you the biggest bonus, and Curse! Keelhauled!, which tells you to "Lose Yer Armor."

In the case of Curse! Scuppered!, you would have to be using the Item in question for it to give you a bonus, and since you were not using Fearsome Tattoos, you wouldn't have to discard the card for that Curse. For Curse! Keelhauled!, since it says to lose your Armor, you must discard all your Armor Items in play, whether you were using them or not, so you would have to discard Fearsome Tattoos.
