a bit not good 

Used in the first episode of BBC's Sherlock, Sherlock says, after asking why a woman would STILL be upset by the death of her daughter, "Not good?". John Watson responds, "A bit not good, yeah."
Later, it became a fanfiction tag, usually on Archive of Our Own, depicting a character in a not very good mental state

Mycroft is A Bit Not Good
"That angst fic had me in tears. Sherlock was a bit not good and John was trying to help him but he was ALSO a bit not good"

STOP UNEXCEPTING MY DEFINITIONS AND UPLOADING MY STUPID ONES. Let me just say, if this gets posted I will shit myself laughing.

It's kind of self explanatory.

I'm Good

Rejection of and ridicule for an offered good or service by feigning satiation. When "No Thank You" just won't do.

Person A: "Would you like to try some of my new recipe? It's Guacamole Crab Dip."
Person B: "No, I'm good"

Person A (on the phone): "Hey, Jenny. You've been studying too hard. How 'bout I swing by your apartment and give you a back rub?"
Jenny: "No. I'm good"

Person A: Do you want to go down to the Creepy Crawl and see The Wheezing Coughers?
Person B: "No thanks, I'm good."

I said good day! 

I've had enough of listening to your drivel. Begone!

As spoken memorably by the inimitable Gene Wilder as Willy Wonka himself in "Willie Wonka and the Chocolate Factory":

Grandpa Joe: You're a crook. You're a cheat and a swindler. How could you do a thing like this, raise up a little boy's hopes and then dash all his dreams to pieces? You're an inhuman monster.
Willy Wonka: I said good day!
