The result of the residue or tar left behind on a person's lips after doing an exceptionally large bong hit or hitting on a blunt or blizzo...usually occuring from the bottom of of a person's bag if it is of high quality pot strain like kush, chronic or indo or from smoking any very low grade pot like schwag weed, brown or mexican bud.
