[Tommy is saying goodnight to his girlfriend at his parents house. An act which his parents mistake for him having sex. His mom pulls him aside and yells "Not in THIS house!"

John: "Dude your sister is so hot!"
Jack: "Not in THIS house!"

Not in my house

In basketball when a shot is rejected, a commentator or the player himself will say 'not in my house'.

Dude, after Mutombo blocked that shot he waved his finger and said 'not in my house!'.

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."

not in the face 

An often hastily imparted supplication for mercy by the receiver of an imminent beatdown unto their aggressor.

"ow-fuck! what did I just say?!"

or in the case of the Chiss bartender from Jedi Academy,

"Please noble Jediss... not in the facess!"
