Get the ninjamug. I was playing a game of GoW and it was only me and this other kid left so I creeped up behind him and ninja'd him with my shotgun, He never saw me coming.

Get the ninjamug. The act a man pulls off when lying in bed with a woman fingering her and then slips his dick in so fast she never has a chance to say she didnt want to go that far.
she was nervous when i started touching her so i knew i would have to be stealth to get anywhere else, my fingers layed the distraction and the ninja got the action.

Get the ninjamug. To get an item from a MMORPG, saying they need it, which in fact they don't.
Then they sell it to other players for Money.
