get off my back

Stop nagging or pestering me. This slangy expression has been popular since the late 1930s, and its precise origin has been lost. It may have come from the older saying, to have a monkey on one’s back, which once meant to be angry or annoyed but since about 1930 has meant to be addicted to drugs. More likely “get off my back” alludes simply to a burden. As governor of California (1966–74), Ronald Reagan frequently used the term, saying we need to “get government off our backs.”
