someone that is so full of shit that every time they take a step a brown spot is left from where their foot hit the ground, thats not tar on their heels, thats definitly some shit

The word Tar Heel (or, Tarheel) is the nickname given to someone who is a native or resident of North Carolina, the Tar Heel State.

The term allegedly comes from the Colonial Era in which tar was one of North Carolina's major products. It came from the workers who walked through the forrest accumulating the tar on their shoes.

A more colorful explanation comes from the Civil War in which North Carolinian soldiers were abandoned by other retreating soldiers to fight alone. Upon returning to the retreaters, the "Tar Heel Boys" told the other soldiers, "Next time we'll put tar on your heels to make them stick," insinuating that they won't be able to flee.

So many Carolinians made their living by and on the water in the early days of sail that they were known by the term for an apprentice sailor in England–tarheel–for their feet were stained with the tar which protected the ratlines, the ladder-like ropes used to ascend the rigging to the sails.

An unnecessary nightcap (UNC).

Faggot polesmokers who worship the queerest color under the sun and swear it's a virtue. To wit: "God must love Carolina, he made the sky Tarheel Blue." Fucking Biff and Buffy wannabe East Coast effeminate types who routinely switch gender roles in twisted rituals involving strap-ons. Often preceded with the word "fucking".
