"Sucker" is a term used to refer to lollipops, a sasal shoot in botany, or a part of a cephalopod limb in anatomy. The term also refers to a gullible person, or a person who can, without batting an eyelash, swallow a load of bullshit whole. Suckers' most significant function in the world is to form a base of support for numerous quacks, cranks, and/or politicians.
Not to be confused with a sucker punch.
