A Ninja Typo is a punctuation or grammatical error that does not reveal itself to the author (no matter how hard the author looks for it) until it is too late (i.e. after it has been published in a way that cannot be retracted).
Example : Dang! I proofread this email 3 times and I STILL managed to leave the "l" out of "turtle". That Ninja Typo just killed my chances of getting re-elected.

Get the drunken ninjamug. After a sporting event; when your teammate is washing his hair and his eyes are closed, someone sneaks up behind him and checks his oil with their thumb (quickly slips a thumb in his ass), then runs off before he is able to rinse the soap away and identify the clandestine violator
After the game someone gave John a rusty ninja. John was attacked by a rusty ninja after the game. Be careful, there's a rusty ninja in there.
