Mr. threadneck

A redneck who goes to a city school and has a reputation of miss spelling words. This person playes video games and rides four wheelers. A person who has a butterfly knife and talks about it way too much, they run with their head first:) This person is super hick but is real fun.

"Do you like Mr. threadneck?"
"what?"
"I meant to say redneck"
"your such a hick!"

Threadjack 

To take over the content of a message thread by changing the subject of discourse to a topic outside the purview of the original subject and/orforum, while maintaining the subject line. A form of amusement for trolls. Threadjacking is distinguished from flaming, as flames are a quasi-personal attack on a poster or on a poster's style of discourse, where threadjacking is deliberatly steering the discussion offtopic.

Arm4war keeps starting threads about how fighting style affects gameplay, but artboy keeps threadjacking his posts with rants about non-real world physics.

threadfuck

when a comment thread leaves the original topic gasping faintly in the distance and becomes a war between two equally stubborn, angry and/or compulsive strangers

Man, as soon as someone dropped the "Nazi" bomb, I knew this was going to turn into a total threadfuck.

threadsecutioner 

Very similar to the Thread Killer, the Threadsecutioner is an individual who kills an online discussion. Whether on a message board or a comment on a Facebook wall post, the threadsecutioner's contribution almost always ends the discussion.

The threadsecutioner's intentions are pure, but his actions are disastrous.

Commenter 1: Climate change is absolutely real! The vast majority of scientists agree on that!

Commenter 2: The science is flawed, and there's a significant number of scientists who think it's all bogus!

Threadsecutioner: Hey guys, here are 16 links to stories about this very topic!
