There was a guy I know who had something similar, except it was this thing like a big pore on his shoulder that never seemed to run out of yellowish semi-solid pus plugs to squeeze out of it. The Everlasting Pusglobber.
I had something like that between my chin and lower lip for a year or so in highschool, it stopped being visible after the first month, but kept being something that always could be squeezed.
