a piece of log so humungous and/or rigid that, after the deed, the defecator would need to flush the toilet twice to completely banish the sucker.  Sometimes it requires the assistance of the defecator to break the shat up manuel with near-by objects, e.g. toilet brush, scissors, toothbrush (of one's partner), etc.

Get the two flushermug. A large, prolonged crap.  It's no fun, and it's so big/smelly that it requires two flushes (generally a courtesy flush and a final flush).
