the green snotlike substance that rattles in your throat when you cough,especially after smoking about 70 cigarettes
the old woman 'hawked' up a large gobbet of 'phlegm' from deep in her throat,and spat it onto a shop window,where it bounced once before clinging to the glass and spreading slightly,waiting menacingly,for the first passerby to brush against it,transferring the green bastard to their expensive designer top so,when they, arrived everyone at the party would look and wonder.
