not in my book

1) that is not true, according to my morals, principles, and beliefs
2) in a place other than the bound collection of literature that belongs to me or rests in my hand

1)
Cop: "Oh man, what a hard day of busting drug dealers it's been. A big fat J would really hit the spot right now. Can I borrow some papers?"
Your square ass: "Isn't that...um...illegal? Smoking marijuana, I mean?"
Cop: "Not in my book. Bitch."

2)
"Damn, a playa really needs to take a piss after those 10 beers I just had. Over here would be a good spot."
"Oh shit!!!! Not in my book!!!"
"Whoops, sorry about that."

in my book

When something is according to your beliefs and ideals. Same as in my opinion

Person 1: Is being a bookworm cool?
Person 2: It is in my book.

taking a page out of my book

Attempting to copy or steal someone's idea or mannerism.

He's wearing a red hat like I do, he's taking a page out of my book .

He is wearing the same hat I do. He's taking page out of my book

my books got diggers

originated from the phrase, "My dicks got boogers". The phrase was then modified for unknown reasons. Mostly used in the Northeast. Probably referencing some kind of STD or genitalia-oozing ailment.

Yo sun sun, i can't believe my books got diggers, I gotta get that shit taken care of, that damn filthy snailtrail.

Those are my mother's books!

As seen in the movie Casino:

1. A poorly-crafted attempt to divert suspicion, despite obvious guilt.

2. Attempting to flee a bad situation with an ill-conceived method of escape.

"Little Craps figures--very nice, thank you very much, Mr. Piscano..."
"Those are my mother's books!"
