Like, you can guess at my pronouns if they aren't obvious to you. I won't be offended. Him, her, they, hey you, buddy, pal. Same with titles. Sir, madam, Xir, lord, lady, whatever. It's no big deal if you can't tell I'm a dude, or your worried you'll get it wrong. That is on you, not me.

My preferred pronouns are the ones in English that used in a grammatically correct way.

Now if approach me saying "surprise, motherfucker" and you are neither a close friend, nor family, not Sgt. Doakes, I will take offense and react accordingly (i.e. I'll presume I'm being mugged).
