hijacked 

the act of intentionally having an off-topic conversation in a thread in order to prevent the thread's original topic from being discussed

When xbabycakesx made a thread in which she posted pictures of her new tattoos, some righteous guardian angel of messageboard crusader hijacked it by posting animated .gifs of nefarious cartoon tubers engaged in devious sex acts, thus preventing her from losing face by shifting attention away from the embarrassing photos she had posted.
