Sirius Black was procrastinating on Defense homework for a very important reason: Remus. His brains being still racked with worries about his friend lead the 4th year to the Magical Medical Encyclopedia vol. 1-87. Currently the boy was thumbing through the B’s.

Or Betrotrickanosa; a common hereditary disease found mostly in males; in which minor 72 hour commas strike the victim monthly.
Bulbaphyrasis, enlargement of the genitals due to inflammation; requires draining assistance.
