threadbreak 

Word used when someone on a message board posts a picture or a long string of words that stretches the page the post is on beyond its normal limit.

That guy made a threadbreak with that giant pic of child porn!!!

Threadbear 

A person who comments on a thread dedicated to a topic they pretend to abhor but secretly find fascinating, if for no other reason than they are compelled to act out a deep-seated impulse to be a total opinionated douche bag. This condition is often coupled with bitchitus and in some people can lead to chronic dickiness.

If one encounters a threadbear squatting on a site, it is best to let it shit then move on without interruption.

Threadwrecker

Much like the homewrecker, a threadwrecker interferes with the natural flow and order of things, e.g. a thread of comments related to a post on Facebook.

That jerkwad is such a threadwrecker on Facebook!!

Post: JANE DOE is deciding between pizza and mexican food for dinner.

NJ: Oh, I would def have pizza!
ST: Have you tried Jose's Cantina? Awesome?

JW: Hey Jane, is your grandmother out of the hospital yet or did she die already?
