Word Association Game
The first Word Association Game thread was started way back when ARRSE was a mere hobby for the COs. The first attempt only survived two or three pages, the second attempt has been banished never to be seen again and Word Association III managed to survive 200 pages (see here) before being banished to the The ARRSE Hole.
But, just like syphilis before the advent of antibiotics, it’s almost impossible to get rid of. The latest version is stronger and longer than ever and can be found here.
