Well, there's only one sensible thing to do. Piss yourself. Once he realises his passive-aggressive behaviour has earned his upholstery a thorough soaking in urine, he'll ensure his disparaging comments are only uttered out of earshot of the subject.

Way to humbebrag about how good your hearing is, OP! How would his father know you have ears like a bat and can hear all the way from the back seat?!

I'm sure he knew you were there, so he was probably just joking. Or really doesn't give a crap, but I'm gonna hope for the former.

While that's extremely rude, you're in a relationship with your boyfriend, not his dad, so as long as your boyfriend still loves you and wants to be with you, try not to let what his dad said get to you. His opinion doesnt matter.

Don’t you just love it when the partner’s parents hate you? NOT.

Wow sounds like Dad was trying to upset you, probably just so you would break up with him🤔

Maybe he wants his son to suck a dick like a champ.

Maybe you should speak up and defend yourself a little instead of being stepped on. Father or not, give him a piece of your mind

What a passive aggressive asshole.

How did your boyfriend handle the situation?
