Someone or something that cheeks, or in some contexts, a device or part that relates to the cheek.
From 'cheek' + '-er' agent suffix. The '-er' suffix creates agent nouns (someone who does something) from verbs. This word is not commonly used in modern English.
This is an archaic or very rare word—you almost never hear it used today because we simply don't need a specific word for 'something that cheeks.' It shows how English constantly sheds words that become unnecessary!
