Full body flushed 

When, after a night of hard drinking, one urinates, defecates and vomits all at the same time. Usually done while on sitting on the toilet and vomiting in the sink or trash can.

Woke up this morning so hungover that I full body flushed myself.

Double Flusher 

When one takes a shit so large it requires two flushes to completely get rid of the shit and any evidence of its existence.

John had McDonald's for breakfast, Taco Bell for lunch, and had to take a double flusher before we even got to dinner."

two flusher 

A dump so enormous that one must flush the toilet twice to get it all down.

Excuse me folks but I must hit the can. This could be a two flusher!

Double Flusher 

#1. To take a crap so big that your pants fit better.
#2. To crap a turd so big, one end is sticking out of the water.
#3. To crap so big around you have to break it up with the plunger and flush twice.
#4. When you take a crap that stinks so bad, you give a courtesy flush half way though. This act cuts down on the room aroma.

Hey Dude, I shit a Double Flusher so big, I heard my butt cheeks slap together when the pointed end came out.

self-flusher 

That turd you do that's so heavy it disappears round the u-bend under its own gravity without you having to flush it.
Antonym of unflushable

Kevin's 6 pound self-flusher landed so loudly in the pan the splash woke his deaf grandma.
