I think it is related to the (in)famous talk the Subversion developers held in 2008 about "Poisonous people" https://www.youtube.com/watch?v=-F-3E8pyjFo https://www.youtube.com/watch?v=-F-3E8pyjFo Both terms are kind of meaningless because the allegory to toxic substances doesn't work at all. Water, salt, alcohol, DDT and lead are all toxic but in different ways. Imo, more specific terms are better like "Help Vampire," which according to some, would be a poisonous person.
