The act of “bumping” a thread is to reply to a thread which hasn’t been active in at least a few months. It’s generally frowned upon in most forums because it moves a thread to the top of a section.
Forum users get VERY angry when people bump threads. I don't care that much though so it's ok that you did not know!
