a colobian harmonica is achieved when a amount of cocaine is poured on the penis; and the penis is in-turn used to apply the cocaine to the gums of another party; typically, of the female gender. See "number"
a colombian harmonica will get a stripper to blow you in much the same manner as dumping beef gravy on your dick would a fat chick
