In British English slang, "gob" is a word for the mouth.
This slang term is relatively common in the UK, particularly in informal contexts. It's often used in phrases like "shut your gob" (be quiet) or "gobsmacked" (astonished, literally 'mouth smacked').
While "gob" primarily refers to the mouth, it can occasionally also refer to saliva or spittle, depending on the context.
