To surprisingly poke an individual while scaring them. To achieve this you must run on the balls of your feet toward the individual while they are occupied with another activity or while they are just not paying attention. But be sure to run on the balls of your feet, as so they can't hear you coming towards them. When you get close enough (while still running) you poke them, HARD! And then run away laughing, because the individual will look hilarious afterwards. They will look like somewhere between the mix of having a heart-attack and surprize and pain.
Look at that person I just ninja poked! It is sooo hilarious!

A poke ninja refers to talented and skilled person who pokes people on facebook using unusual and crafty methods. Poking in a ninja manner involves stealth, speed, mastery of various poking options.

Suspected to possess jedi-like powers, a poke ninja can poke using household objects, different programming styles, small rodents, and has an uncanny ability to dance in a 50s swing style to any kind of music, except country music.

Poke ninjas appreciate chaos, pickles and have been known to lick randomly people.
James is such an amazing poke ninja. Jessica was a pokecamper, and when he poked her, she didn't even realize it.
