threadsitting 

When the OP of a thread constantly replies to other peoples' posts in it. He or she is most likely F5ing frequently to look for new posts.

Also known as threadcamping.

OP: What is your favorite color? Mine's Blue.

Poster 1: Red.

OP: Oh cool! Red is neat too.

Poster 2: I like green.

OP: Eh, green is OK, but it's not for me though.

Poster 3: My favorite is yellow.

OP: Yeah I don't get yellow at all! That's so weird!

Poster 4: Pink's the best.

OP: How did you know?! Pink is my second most favorite color!

Poster 5: Orange, and stop threadsitting.

OP: Oh please let me threadsit, I lost my job and broke all my limbs and the only things I have left in the world is this thread, and my 50 cats :(

thread-shitting

Posting off topic messages to a discussion forum. Usually, but not always, with purposeful intent to derail the discussion.

Example post for thread-shitting:

"I just ate a huge bean burrito for lunch! There really wasn't enough cheese in it, but the extra Pico made up for it. It was quite satisfying."

What golden canadian robots do on threads they don't personally like.

3PO: If it weren't for me arguing, this thread would die, so you should THANK me. It is definitely not thread-shitting.
