An online video that when released attracts so much traffic that it crashes your site, the same way a blockbuster movie sells out theaters.

"Dr. Horrible should prove to be a profitable venture in the end, and will probably establish itself as the 'sitebuster' hit of the summer..." – Tubefilter

Shitbuster 

When you know someone is taking a shit, you run in the bathroom during the shit and you yell,
"ARE YOU TAKING A SHIT?!"
and the other person will prob be like,
"GTFO"
and you say in a high pitched voice.
"BUSTED"
then exit the bathroom.
After you complete the task completely, you are now officially a shitbuster.

*Friend Goes Into Bathroom and Sits Down To Take Shit*
*You wait 2 minutes then run into bathroom*

You: "ARE YOU TAKING A SHIT?!"

Friend: "Yeah GTFO BITCH!"

You: "BUSTED!!" (In High Pitched Voice)

You are now officially a shitbuster.

Spinebuster 

In pro wrestling, a spinebuster is a move that involves a wrestler picking up his opponent, spinning, then finally slamming them down onto their back, or spine.

"CW Anderson finishes with a spinebuster."

Spinebuster 

The Spinebuster is a professional wrestling move developed by Arn Anderson. It starts with a wrestler lifting his opponent with his arms with the opponent's gut on the wrestler's shoulder. From here, the wrestler spins 180 degrees, pulling his opponent's legs while apparently kneeling and pushing the opponent with his shoulder to slam the opponent by the back in the mat. This move is commonly used against charging opponents.

Other wrestlers do not spin 180 degrees and simply execute the slam. Due to this non-spinning version, to avoid confusion, the original Spinebuster is sometimes billed as the Spinning Spinebuster. There is also a Running Spinebuster, where a wrestler runs to an opponent, lifts the opponent up while running and slams him just like in the non-spinning Spinebuster.

Batista showed great raw power when he hit Viscera with a Spinebuster.
