A chlamydia/herpes super virus, first diagnosed on the campus of the University of British Columbia in fall of 2009.
Symptoms include: attractiveness, guilt trips, baseball skills and inability to sleep in your own bed.
Although a new and somewhat rare disease, students of UBC have taken to wearing brown ribbons to support "Clerpes Awareness Week".
Clerpes Awareness Week is observed any weekend when someone with the last name "Brown" has sex.
Hey, that guy totally got Clerpes from the girl at the Pit Pub.
