A ninja boner is an erect penis that you must stealthily conceal whilst moving, which involves disguises and clever use of shadow and vegetation.
Often required when the words "Give it a minute" will not save you.

Last night Jen gave me such a ninja boner at the party, I had to creep around the outside of the garden in the dark to get a drink.

Boobs you wouldn't really think are big from an "in the shirt" perspective, but when released from captivity they sneak up on you and are huge. Like a ninja
I didn't realize her boobs were that big until she took off her shirt, they were totally big and amazing. I love her ninja boobs.

An internet-savvy person who knows about numerous websites, blogs, etc. and how to get the most out of them. Anyone can use Google to find something after enough digging; but an internet ninja knows exactly what websites to go to for immediate answers or solutions. They are swift and lethal, in and out before you even know it...with whatever they want--just like a ninja.

Going to a large shop or store, typically a supermarket and getting in and out really quickly. To just buy what you were going in for without getting delayed by special offers or little old ladies getting in the way.
Max was out of the store with the beers before they guys had even found a good parking spot. Thats why they sent him, he was the best at ninja shopping.
