A Black Sabbath song. Contrary to common belief, "N.I.B." doesn't stand for "Nativity In Black," in fact, it doesn't stand for anything. Drummer Bill Ward had a beard that singer Ozzy Osbourne said looked like a pen nib. The band named the song after the nib and added initials so the name would be more mysterious. There are two Black Sabbath tribute albums named Nativity in Black, based on the faux acronym.

I accidentally got a boner when we were watching the video on herpes in class today, luckily I was nibbing the entire time and no one noticed. Phew!
