Trolling as we know it was invented by Socrates and called Socratic Irony. It was performed IRL. Unfortunately, primitive people found irony confusing and scary, so they forced him to drink hemlock and die. The technical term for rhetorical trolling is eristics: "Arguing for the sake of conflict as opposed to the seeking of truth".
The Bible writers were the OTs (original trollers). They were so fucking good people are still RRRAAAGGGGing over that bullshit today.
In the picture to the left we see trolling as it happened for the first time, when The Devil trolled Eve into eating the apple.
Quite possibly one of the lulziest cases of historical trolling occurred in 1857 in the British colony of India. The British included native-born soldiers, both Muslim and Hindu, into their army, and then royally pwned their asses by putting pig grease on the bullet cartridges for the Muslim soldiers, and cow grease on the bullet cartridges for the Hindu soldiers. These are paper cartridges, mind you, and every soldier was trained to bite open the wrapping in order to pour the gunpowder down the barrel. It was later recorded in the respective holy books of the two religions that every one of these soldiers burned for eternity in sand nigger hell.
Much lulz ensued until the Hindus and the Muslims found out and staged a revolt. Then the British killed them all, and even more lulz were had by all.
In the early 1700s two English writers, Trenchard and Gordon, trolled the English government with their Letters to the Editor, that were collected and published as Cato's Letters. These were extremely popular in the colonies and provided some of the arguments for American independence. Without trolling, America would not exist.
Trolling was later taught as a college-level course by Professor Tim Pierce, resulting in Wikicide.
U.S. courts have found that trolling is a Constitutionally-protected right (See the lulz here). Recently, trolling has been destroyed by retards who think that trolling is just spamming the same word over and over.
Another example of early trolling was in 1972 with the release of the film known as Pink Flamingos which had people eating dogshit!
