Mostly bound — rarely stands alone in modern Chinese. You'll see it in 鄙视 (to despise), 鄙夷 (disdain), 卑鄙 (despicable), and humble self-references like 鄙人 (yours truly) or 鄙见 (my humble view).
history
Originally meant 'rural border district' in the Zhou dynasty (五百家为鄙 — '500 households make a 鄙'). The 'lowly/crude' meaning came from contempt for rural outskirts vs. the capital.
