Thats the best I could describe it. Smells a lil off.
If you smoke weed your lungs are going to try and expel the tar from the weed smoke (or cigarettes or whatever) but as its sitting in your lungs and sinus cavity its accumulating bacteria.
all i know is i just blew out a big booger in the bathroom.. that shit was huge. bigger than my thumbnail. Oh yeah and i dont smell anything neither and im hella sniffing.
