If anybody at Matasano is reading this, I want you guys to know something. In South America, matasano (also one word) transliterates to "killer of the healthy" and means "doctor who does more harm than good." It's slang, of course, similar to "shrink" and connotes...exactly what it means.
Interestingly tptacek commented on this saying - 'Matasano' ==> 'Last doctor you would go to'. And they were sad for a few minutes and then were 'very happy' with the name.
The implication being that 'Matasano' is the last doc you go to who 'CURES' you I guess...
