Thread Jacking 

Taking over a thread on a message board by taking a part of the original posted topic, twisting it around and "hijacking" the thread itself. What happens is that the original content contained in the post becomes moot and whatever the "Thread Jacker" has manipulated the content to be becomes the new content thereby "hijacking" the original intent of post. People now respond to the "thread jacker's" input and the that becomes the focus of the tread.

LK25 did an excellent job of thread jacking Koko's post on Dennis Landolt.

Koko's posted topic on Dennis Landolt (PSU Football player) and comments regarding his development on Penn States FOS site becomes indictment of whole offensive line:

KokobewareHI: "Why do I feel like this thread is about to get hijacked? What happened to my original question?"

PSUnittany: "LK25, the thread was about Landolt & his progress...and (of course) you spin it into another "the staff is lazy at recruiting - we are doomed!" threads...It's so tiresome. Please link me to any threads that you don't hijack & ruin. Thank you."

OCCalif: "Although LK25 has jacked this thread to a degree, I feel his concerns are somewhat valid- we should be concerned about our offensive line."

Jack Threads 

An advertiser on Urban Dictionary that promotes ridiculous Nigger costumes as "mens wear". Also any clothing worn while jacking off.

I wouldn't even wear Jack Threads to masturbate. I prefer a wife beater and boxer shorts.

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.

No one threadjacks our forum on the possibilities of inter-galactic peace through (extremely impressive) multi-part harmony singing!

Threadjack 

Definition:

To hijack the engagement arc of a social media thread—usually via a high-impact comment that pulls attention, likes, and replies away from the original post. A threadjacker shifts gravitational focus, often triggering Screenshattin attempts and clout siphoning.

“He dropped one line and threadjacked the whole post—now everyone’s replying to him instead of the original video.”
