The back of (one's) hand has been used to imply contempt and rejection since at least 1300; to know something like the back of one's hand, implying familiarity, is first attested 1943. Back bench in the House of Commons sense is from 1874. Back-hand as a tennis stroke dates from 1657. Back-talk "impertinent retort" is first recorded 1858, originally often used in literary attempts at low Irish idiom. To be on the back burner in the figurative sense is from 1960.
