Irregardless (the fact that this is now a real word makes me hate everything. It's regardless. The negative prefix and negative suffix together are redundant and clunky.)
'Well, the Bible says...' (no explanation necessary)
'Meat is murder' (this one grinds my gears. Most forms of food require the death or abortion of an organism or its offspring, I believe that being aware and morally outraged about only one side of that equation is folly. As animals, we are consumers. Industrial meat farming as an issue is a fucking nightmare though, so I'm with them on that. I'm not arguing with vegetarianism or veganism, just the moral self-righteousness of the idea that killing a chicken to eat is wrong but aborting an apple tree to eat isn't. Death of organisms to replenish nutrients is a thing, maintaining a less meat-centric diet as omnivores is a totally valid issue.)
Mentioning being a Patriots fan or a Duke fan (for some reason every vocal Pats or Blue Devils fan I've encountered so far has been kind of a reprehensible, self important douche.)
People who refer to their favorite sports team as 'we' like they were on the field/court doing a fucking thing.
Bae (oh I missed the second b in babe I guess I'll start an idiomatic trend)
THOT (it's an acronym, the fact a lot of people who use it don't understand that irks me in addition to the term itself)
ATM machine (the hell you think the M stands for?)
Squad (are you military? A firefighter? Some other form of uniform-wearing group? No? Then you're not part of a squad.)
YOLO (at least the guy who coined this phrase apologized)
'Keep it one hundred' (you can't just say 'being honest' or 'being loyal?' )
"On fleek" (what the actual everloving fluck.)
Anything pro brexsit. I'm sick to death of un educated racists thinking that this will make Briton great again!! First of all: Your all to young to know Briton without the eu
Secondly: how can you not see its all so the torys, there new labourite clones and the rich elite can keep there tax affairs a secret and bulldoze workers rights
Pretty much everything already mentioned save for sports stuff, as I really could not care less about sports.
Allow me to add
'I could care less,' which means you do care.
'YAAAAAAASSSSSS'--the fuck is that noise?!
Typing elongated words by repeating the consonants, for example, 'thisssssssss.' What are you, a leaky snake?
I'm sure I'll come up with more.
