I'll start with one that isn't really related to chuds or fascists, but it still annoyed the hell out of me for years:

"Wow, really? Seriously? Wow, just... wow" as a method of snark carpet bombing. I hated how little substance such remarks and responses had. They were used everywhere for a while about almost everything. The worst moment of its use was when I was at a social function and someone I knew belted out "wow, really?" while looking at me and people around me. I asked what the matter was, and got "seriously?" as a response. Then he walked away saying "wow, just... wow." To this day I still have no idea what exactly happened there but he must have felt very smart and quippy about it.

I blame Lisa Simpson for that one. Maybe it was the last gasping moment of Simpsons cultural relevance, like a noxious gas wafting from a dying body.

I'm very, very happy that "gay" as an insult has lost its teeth outside of the most isolated chud bubbles across the internet. Sometimes I do see it used, but it's often at the expense of the speaker, making them sound really out of touch, even old. It's even better when they get mad at people for not taking it the way they want it to be taken.

"I am socially liberal and fiscally conservative" is practically a punch line now. The few times I still see it, even in public and offline, it's often from the kind of person that is so out of touch that they still think Brad Pitt is every woman's dream date.
