Also known as BAS. When you take a really thick slam and the turd breaks off early, but you don't know it so you wipe black doodey all over yourself.

BAS attacks over 2 million Americans every year. However, there is something you can do to stop it. Swing by your local library and tell them you would like to help in the fight against BAS. Together, we can make a difference.
