Where did the term gob referring to sailors come from?
There are two theories on this one. This term first showed up in regard to sailors around 1909 and may have come from the word gobble. Reportedly, some people thought that sailors gobbled their food. The term also may come from the word gob, which means to spit, something sailors also reportedly do often. English coastguardsmen were referred to as gobbies because of their spitting habits.
