Ninja Scrolling 

The act of sucking a girl's tit whereby the person totally puts the whole thing in their mouth or almost manages to do it while making a sucking like sound. Has nothing to do with rape.

It is derived from the gratuitously sexual and violent anime called Ninja Scroll. An antagonistic character T'ssai rapes one of the main protagonist women, Kegaro, where he literally had one of her porn star tits completely inside of his mouth. It was the most hilarious scene in Ninja Scroll.

He is so ninja scrolling his gf tonight.

ninja compliment 

When you compliment someone, but it first sounds like an insult, (and probably is). Called a ninja compliment because the compliment is in there, but it's as hard to find as a ninja.

Janet: "You look great now you're not so fat. Before you looked really bad"

Jane: "So, she said I looked really bad before, but I'm better now I'm not so fat."

Jill: "Wow, so a ninja compliment then...."

Penis Ninja

Penis Ninja is the Ninja of the peen and is sometimes used to insult someone but mostly used as a reference for an awesome event that has happened.

It is also used as a random ninja attack phrase when trying to scare someone or when trying to invoke the spirit of the Penis Ninja"

"Hey did you hear Justin Bieber's new single"
"Justin Bieber's sucks ninja peen"

"Hey did you take my last Kit-Kat?"
"Yes, why?"
"In the dark of the night I'm going to send the Penis Ninja after you to kick your ass!"

"PENIS NINJA!!!"

Getting 'ninjaed' in Halo 3, is when somebody jumps backwards over your head and assassinates you.
