When you clog the toilet with one large turd. The turf tends to just kind of waller around in there.
Hey, do you have a plunger? Just had a one logger clogger. Yeah, man. No U-bend for this thing. Gonna have to chop it up
When you gotta take a big shit, and you drop it all in one steamy log, rather than many shits. Its glorious and sought after by many cultures. Some say it's where the term "holy shit" derives from. A one-logger must be chosen by God, and cannot be artificially induced, thus banning the faux-logger.
