An individual who constantly drops thread bombs in online forums or message boards that kill any future comments. Thread bombers may be clueless people who honestly think they are adding to the discussion or douchebags who intentionally ruin the thread.
That girl I added keeps posting the most awkward things on all my friends comments. I should unfriend that thread bomber.
