When you read the twitter updates of someone and you see an outrageous directed tweet and you want to know what led up to that tweet(or update) of theirs -- you must play ping pong between the 2 users to see who asked what and why it was answered that way.
JessicaDoe: @JoeShmoe I like them big and firm.
original tweet-
JoeShmoe: how do you shop for oranges?
I had to play tweet ping pong to find out why Jessica said "I like them big and firm!"
