Busting Your Chops
Meaning
To say things intended to harass.
Example
Don’t get mad, I am just busting your chops.
Origin
At the turn of the century, wearing very long sideburns – called mutton chops or lamb chops – was en vogue. Lamb chop side burns also made a comeback in the late 1960s. A bust in the chops was to get hit in the face. Since Mutton Chops are no longer considered high fashion, the term has come to be figurative rather than literal.
