I once met a guy who could shoot streams of saliva
from his salivary glands. This was not spitting
, nosiree, he would do this with his mouth completely open, set himself up, and two gentle arcs of saliva would come spurting
out of his mouth like tiny fountains
He said he had taught himself to do this with years of practice. I think we've all accidentally had saliva shoot out of our mouths, so it seems possible that you could train your body to do it on command, but that doesn't make it any less freakish.
