Avoid publicity or attention, try to be inconspicuous. The term dates from the mid-1900s. William Safire suggests it may have originated in the military, where tanks and other armored vehicles are less vulnerable when they present a low profile. Another theory is that it is a translation of the Japanese teishisei, for “low posture,” the motto for Hayato Ikeda’s cabinet of 1960–64. It is now used in a large variety of contexts, ranging from politics (as in, “Let’s keep a low profile on abortion rights”) to celebrities in various fields.
