Here's how it goes:
Someone posts, and the next poster has to guess the age of the previous poster.
It's a semi-fun way to find out about people's age and to up postcounts.
It also might be remotely entertaining for anyone mildly drunk, bored or retarded.
For starters, I'll guess the age of the last poster in the 1000th post thread; Kermit:
...18
