Is them then overly mocking you for not getting the joke and acting like you're so super stupid for not getting their offensive pun in the first place.

I should feel like I'm a good person for not understanding something offensive, but I feel both stupid and angry! And she won't shut up :(

Also overheard at work today, from my male co-worker who thinks he knows about 14x more than he actually does know, and says everything in that implacable voice that sounds like there is absolutely no other opinion to be had other than agreeing with what he is saying:

"Yeah, I like XYZ bar but I feel like they actually screw you over on getting a full pint of beer, because they use those mason jar glasses"

You mean... those glasses that are exactly a pint? Yeah, you're totally being persecuted, as per usual.
