Threadator 

A person who's post's seem to always ruin an ongoing comment thread. They do this by going off subject, insulting others, or by not understanding the context of the remarks. Basically clueless. Ruins the thread for others.

The "Threadator" killed the thread. No one ever wants to post after the "Threadator". He is such a Threadator.

"Oh, and btw, I wrote the blog with you in mind..ya big hunk.....

Okay, threadwhore, get off my thread and on to someone elses.....

Threadtard 

One who disrupts the pace, ryhthm and progress of a Facebook thread by means of their insipid, irrelevant or offensive comments.

Allison: That was some funny shit that got posted last night!
Rhonda: Yeah, until that threadtard jumped in and sent the whole thing spiraling into the crapper.
