v. Thread crapping occurs when a person comes into a thread and posts something contrary to the spirit/intent of the thread, often derailing the discussion or turning it into an argument.
Coming into a thread titled "I love my new Apple Macintosh!", and posting "PCs are better and cheaper" is thread crapping.
