Roof Ninja

1. In modern First Person Shooters, these are the players that find the highest spot in the map or some inconspicuous place on a ledge until they time it just right to attack.

Then, they proceed to camp in that spot again until the next victim. They rarely leave that place because they have deemed it the most advantageous spot to camp, hardest to reach to counter-attack, etc.

(often a glitched spot in CoD or a place worthy of expert UT trial runners)

Any game of Call of Duty, BF2, Unreal Tournament.

"Zomg will someone kill that roof ninja. He is a no talent ass clown who sucks at camping."

ninja spider

A spider so clever in its hiding ability it is never seen, preferring to live its life in the shadows.

I kill every spider I see, now only the ninja spiders remain.

boo ninja

A Boo Ninja is a man who consistently scores women which are obviously way out of his league. Most often the Boo Ninja is spotted in bars working his magic. In this setting the Boo Ninja will look much like a scout master holding court with his young charges gathered around a camp fire. But the Boo Ninja is no scout master and his charges are not suburbanites but rather really hot young women and with each word the Boo Ninja speaks his audience will either laugh or compliment him on his wisdom as each competes to be his paramour {fuck} for the evening.

"Look at that bald fat fucking old Boo Ninja... he is old enough to be their fucking grandfather, he had the damn valet park his Yugo and yet look at all of that fabulous {highly fuckable} , boo {pussy} hanging on his every word like he is some fucking mullah {Islamic preacher} issuing a fatwa {religious decree}.

Dirty Ninja

A sexual act performed by a man for his partner. The man will shit on the face of his partner then wipe it off of the eyes in a horizontal direction with his penis. The partner will be left with a shit-mask resembling that of a ninja. Then, the man will insert his shit-covered cock into his partner's mouth when they are least expecting it, thus leading the partner into a ninja-like attack stance by the sudden insertion.

Steve begged me for a Dirty Ninja last night but I decided to use a nicely aged Alaskan pipeline on him instead.

Ninja Nerd

A person who hides how much of a nerd he is by acting normal majority of the time. Only his closest friends know how much of a nerd he is while others are unaware.

Joel is such a ninja nerd, he acts normal but we know he's a huge geek deep down.
