When two or more members of an Internet Forum post back and forth trying to express their opinion on a subject. The conversation turns into a posting war and the discussion usually ends up going nowhere.
Poster A: My opinion is that Xbox is better than PS3
Poster B: No I don't agree, PS3 is better
Poster A: Are you crazy? you're so wrong
Poster C: You two are both wrong, Wii is better than both
Poster A: You're joking, right?
Poster D: This is turning into a game of Posting Tennis
