Example: I post the first two words.
Tea Party
The next person follows me and changes one of the words:
Birthday Party
The next person follows that and changes one of the words yet again:
Birthday girl.
You always keep one of the two words --- and you change the other one, so that the two words still comprise a common phrase.

No point having a duplicate thread.
