How mysterious Niffy can be
by Nymphadora Tonks July 17, 2018

A person who has uncontrollable body odour in the arm pit area, so potent that you can smell them before they have even entered a room, most commonly found in gyms, chaz zones and university common rooms. Named after early a Hollywood star Zasu Pitts.
Jeez, I was on the treadmill this morning and the dude on the machine net to me had really niffy Zasus. It was so bad, he should have carried a biohazard warning.
