1) An activity where one person pokes
another person and the other person pokes them back, resulting in a continuous 'Pokewar' - the end of which may never occur.
2) Similar to the above, except that the pokewar is hosted by some form of social networking site - eg; Facebook
1) Pete: "POKE!" *pokes Sally*
Sally: "Hey!" *pokes back*
Pete: *pokes back*
Sally: "Don't turn this into a Pokewar!" *pokes back*
2) "Me and my friend John have been at our Facebook pokewar for three months non stop! I hope he gives in soon, I'm gettin tired of it"
