I was tagging this electrical box at the intersection with a fat drippy marker when the nib fell out and landed in the dirt.

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.

Your love for me has just got to be real

A Black Sabbath song from their first album. The Abbreviation is often misinterpreted as "Nativity In Black," but instead was simply what the band called their guitarist's goatee at the time.
N.I.B is one of my favorite Black Sabbath songs.

The act of licking one's knuckle, punching a man on a ladder's taint with the wet knuckle, and then flicking his balls and inserting a pinky into his anus. Usually performed by one man on another.
Oh my god, I totally want to Nibs that guy on that ladder.
