spiderman thread 

A message board posting technique designed to end or derail threads that its user finds uninteresting or lacking productive discussion. This technique involves posting screencaps from the 1967 Spider-Man cartoon series with humorous captions unrelated to the original thread topic. The user generally initiates a Spiderman thread with captions intended to declare that the original thread topic will no longer be discussed. Occasionally, additional users contribute to the derailing with their own screencaps of Spider-Man. Frequently used on 4chan's various message boards, where the technique originated. Generally used to derail threads about incest or "wincest."

Wincest? That's a funny way to say Spiderman thread.

Threadbanger

A YouTube channel by two people, Rob Czar and Corinne Leigh.
They make some cool DIYs from Pinterest, but have other series too.
Corinne is normally sensible and careful, but Rob doesn't care about his health and safety generally.
There are several drug jokes, excessive swearing and blood in their videos.
Currently they have almost 4 million subscribers (July 2017)

Me: I was binge watching Threadbanger today.
Friend: Oh god, you must have seen so much stupidity in such a short time!

Thread Stalker

A person who goes from thread to thread on a message board oblivious to other posters, addressing every post you write and rehashing old gripes based on a personal issue they have with you.

John: I am glad someone created a topic about rude drivers. I hate it when people cut me off on the freeway!

Jane: Oh there you go again John! Just like I told you before, you never have kind words for anyone. I noticed you have a problem with people ever since your thread about your sassy, freeloading cousin. You need to get therapy if you can't handle rude drivers and family members, etc. etc.....

John: Jane, you go into every thread I am in and derail it with your personal issue with me. You're nothing but a thread stalker! There's other posters on this message board, you know.
