TIPlague
From the archives of TiPWiki, the unofficial Duke TIP Wiki
TIPlague is when everyone gets a cold in the middle of summer, usually during the second week of TIP. It is uncommon to not get TIPlague. Consider yourself lucky. TIPlague also varies in severity. Some have it for one day, while others have it for the majority of TIP.
Remember to wash your hands. All. The. Time.
