Being an ass to get reactions out of people and then laughing at them for taking things way too seriously over the internet.
Some people call it trolling or baiting, but it is neither. E-baggery elevates itself to a class of intelligence, being the internet equivalent of satire. The idiots just get left behind.
"Dude, did you see the comment I made on Jane's myspace? It made her cry."

"I have a BS in E-baggery."
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.

Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
