Americanisms unless the poster is American....
"Can I get" instead of "can I have"
"Pissed" instead of "pissed off" (for annoyed)
"Enough already". Urgh!
"I'm done" instead of "I've finished"
"I'm good" instead of "I'm fine"
"You go girl". ODFOD
"My bad" instead of "my mistake"
And other fuckwittery...
"Myself", "yourself" etc used incorrectly
"..., my friend". People are usually not referring to a friend.
Sentences starting with "So,..." eg, "So I was talking to my mum the other day". Stop it, you don't need to put the "so" in front and it makes you sound stupid.
"We're pregnant", when describing a heterosexual couple where, obviously, only the woman is pregnant. "We're expecting a baby" should be used instead.
"Cis woman". Fuck off, I'm a woman. Call yourself a transwoman if you want but don't you dare relabel me.
