A trip to the bathroom that is so massive that the toilet can not handle it all in one flush. One must often flush multiple times to deal with all of the toilet paper that comes with a large dump of this nature.
Martin: Dang, you were in the bathroom a long time.

Steve: Yeah, that was a real multi-flusher.

Get the multi-flusher mug.
A term used by the popular action hero "Killer Bean" in Killer Bean forever, it is here that it is shown Killer Bean has the ability to flush double-flushers with just one flush.
(Killer Bean walks out of the bathroom after a flush is heard)

Killer Bean: "Double-Flusher."

Bartender: "But you only flushed once.."

Killer Bean: (Shakes his head and shrugs)

When requiring three flushes to remove all fecal matter from the toilet.
After cloging the toilet with poop, Jermoe flushed three times and said, wow! A tripple flusher!

1. Somebody who is obviously lying, posturing, idly boasting, who does not have the goods; one who is 'so full of shit' that it would take four flushes during the movement to clear the bowl.

Originally from game of poker, c.1880, one who bluffs that they have five cards in a flush when they only hold four.
Steve: Phil doesn't really have a summer house?
Bob: No, he's living with his parents. He's a lying, four-flushing sack of shit.

A shit so immense that a single flush is insufficient to fully clear the bowl, therefore requiring one to flush the toilet twice.

A crap so massive that it requires two flushes to cleanse the throne.
Whew! That double flusher wore me out! Red beans and rice do it to me every time.

The feeling felt after flushing prior to proper examination of one's stool.
It was quite possibly the heartiest stool of my life. But I'll never really know. I'm suffering some serious flusher's remorse.

Get the Flusher's Remorse mug.
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.
*flush*
dang, still here?
*flush*
later, sucker

"I had a two-flusher this morning mom!"
